I was just cleaning up some bookmarks and I found this. Cheers Mike

Not exactly on topic but here is a great download (175mb) of a book printed in 1973 by Bill Fisher & Bob Waar, it's titled how to modify Datsun 510 610 240Z engines & Chassis. http://datsun510.com/index.php?/files/file/138-how-to-modify-datsun-510-610-240z-engines-chassis/ Lots of great period stuff and some interesting 240z suspension mod info starting on page 212.

Another one of those cases where @jalexquijano likes using the shot gun approach to forum use. Same question asked twice, days apart. Good forum etiquette would suggest that an original poster acknowledge that another topic answered all or part of his new question. Or maybe he was hoping for a different answer.

I went out and had a closer look from behind the dash and I think that plate is actually installed on mine, on the inside. Here is a picture where I have marked what I think is the metal plate you are talking about.

I recently had the heater control panel and radio partially dis-assembled and I don't remember seeing the metal plate you mention. If I just didn't see it, it was definitely not between the radio face plate and the front side of the control panel. Can you post a picture of the metal plate. Like you said the 1970 FSM is not greatly detailed but on the picture on page BE-25 does not show it. Are sure that plate was not part of a previous after market install.

No problem, glad to help.

Back to your original question, I found this explanation of Euro-Metric tires on ModernTireDealer.com. They note that If the aspect ratio is not stated in the tire size then it is 82 by default: From Modern Tire Dealer: Three sizing systems are employed today for passenger tires: P-metric, European metric and alpha-numeric. The most common system is P-metric. The size designation indicates cross section in millimeters, aspect ratio, type of construction and appropriate rim diameter. For example, a P235/50R16 describes a tire that is intended for passenger use (P), and features a cross section width of 235mm, an aspect ratio of 50 and radial construction (R). It needs to be mounted to a 16-inch diameter wheel. European metric, also called metric, is similar. No letter "P" is used as a prefix. The three-digit number at the beginning indicates cross section in millimeters. If the aspect ratio is lower than 82, the aspect ratio number will follow the section width number. If not, then no aspect ratio number will appear. The next letter indicates the speed rating (sometimes the speed rating is included in a P-metric size after the aspect ratio). The R again refers to radial construction, and the final two-digit number indicates rim diameter in inches. One example of a European metric tire size (with an 82 aspect ratio) is 155SR13, which indicates a 155mm section width, an S speed rating, radial construction, and a 13-inch wheel. Here is a link to the full article: http://www.moderntiredealer.com/article/311243/understanding-tire-dimensions Here is another link that lists 225R15 as a Euro-Metric "82" series tire: http://www.tirerack.com/tires/tiretech/45_conversionchart.jsp HTH Mike

165 HR 15 OD = 646mm (25.4") = 80% aspect ratio http://www.michelinclassic.com/en/Classic-Tyre-range/XAS

Sorry for the confusion, I just found this link with a bit of information that may help: http://www.michelinclassic.com/en/Classic-Tyre-range/XVS It list dimensions for an XVS 185 VR 15 and shows an OD of 675mm (26.6") that would be the equivalent of an 80% aspect ratio as was suggested by @Martzedcars above. I'm assuming that the XVS 225 VR 15 would use the same aspect ratio. Also here is a link with 225/70 VR 15's: http://www.michelinclassic.com/en/Classic-Tyre-range/XWX HTH Mike

Even at 70 aspect ratio that would be a large tire. 225/70R15 would be about 27.4" OD and a stock tire for our cars would be under 25" OD. On a '77 280Z from the FSM the stock tire is a 195/70HR14 which has an OD of 24.75".

Great to know about the copyright release from Nissan. Too bad the Courtesy Nissan CD is outside that scope, here is their boiler plate agreement. COURTESY FSM CDROM USER AGREEMENT.pdf

Nice. That wasn't so painful was it.

And how am I going to get any work done this afternoon when you leave us hanging like that.

Not actually downloadable due to copyrights but I purchased to 1970 FSM & S30 Parts catalogs from Courtesy Nissan back in '05. The FSM CD looks to be a scanned copy of the 1970 FSM created for the Nissan Vintage Z Program from 1997. The back cover image on the CD has a Issued Date of March, 1997 (010240), the number in brackets is the same as the 1st November 1969 printing of the 1970 FSM Body & Chassis Volume. The quality of the scans is not that great but the pdf's are searchable and have links from the table of contents. Anyone else have these, and what are your thoughts.

Congrats, any sneak previews on the next one.

Thanks Mike. I fixed the file names but when I went to upload a new zip file I found that my WinZip license just expired so I had to upload the individual .pdf chapter files instead. At least this way is better for mobile device users.

Thanks @jwtaylor and @SteveJ for the feedback. I played around with the scan settings looking for a balance between file size and quality. I have noticed that I made mistakes in the file names of the FE and WT sections. Not a big problem as they can just be renamed after unzipping. I checked to see if I can replace the zip file in the downloads area but didn't see an option, maybe @Mike could chime in and let me know if this is possible.

Just uploaded for those who might be interested. Mike

Not sure on the exact SN but both my 7/70 HLS3006521 and 12/70 (parts car) HLS3016531 have the early steering wheel without the perforations in the indents.

Thanks 26th-z Thanks for posting this Kats, earlier this year I scanned and uploaded the Datsun 240z -260z section of the 1975 Mitchell Foreign Car Collision Estimator Guide, it's in the Service Documents category in Downloads here. I wonder if the estimating times Mitchell used came from the Nissan collision estimating sheets like you have posted?

No problem, I will post here when it is available for download. Sadly it will be "Body & Chassis" only as I don't have a copy of the "Engine" volume. I picked the FSM locally from a craigslist ad a couple of years ago. It was advertised as a two volume 1972 set but when I checked with the seller he realized that it was actually two copies of the Body & Chassis Manual, one 1972 and one 1970 but no engine manual, so I'm still on the look out for a 1970 engine FSM volume. The good thing was I got both copies for $30 and he threw in a copy of "How to modify Datsun engines & chassis 510 610 240Z" by Bill Fisher and Bob Waar printed in 1973. Lots of great historical reading.

I really don't see any issue with the integrity or honesty of @tse4me with regard to this potential sale, unless he actually backed out of an "accepted offer". His original wording regarding the price was "Looking to get 8-9K for it". To me this is not a fixed price and could be interpreted as "8-9K OBO" until a firm offer is accepted. But that's just me.

Just wondering if you have noticed any/many differences between the 1NOV69 and 15AUG70 printings?

The printed copy that I have is same issue date as @26th-Z, 15AUG70 and has all pages but the binding has come apart so over the next few weeks I will create a higher res copy to upload for those who are interested. Here is a sample section: 1970_FSM_ER_Engine Removal_[15AUG70].pdf
