Does anybody here have an old Interpart catalog? I would like to find out the manufacturer and part number of the strut inserts they used to sell.

For 70/71 240-Z

KONI Adjustable Front Shock Absorbers #35-1410 (BRE Part Number)....$43.00 ea

KONI Adjustable Rear Shock Absorbers #35-1411

As of 2-1-72 no KONI's were yet available for the 72 Model Year.

FACTORY 240-Z Racing Suspension Kit #35-1510

Special struts, springs shocks, front and rear anti-roll bars combine to turn your 240-Z into a real handler. Factory designed for minimum installation effort. $552.10 for the kit

FWIW,

Carl B.

Thanks, Carl. Any idea what part numbers 35-1501 and 1502 might be? I'm told they are Interpart strut inserts for 240Z/early 260Z, and that they may be Mulholland. Thoughts?

In the 8-1-72 Interpart catalog they show Carl's data and add the numbers for Konis for 1972:

Front #35-1412

Rear #35-1413

In the 2-1-73 Interpart catalog, they show the 1412 & 1413 numbers as "240-Z all years"

Also in the 2-1-73, they start listing the "Mulholland" inserts with a new numbering scheme:

Front pr. 2351501

Rear pr. 2351502

As a side note, the Mulholland inserts are what I installed in my car back in '73 along with the rest of the Mulholland package.

Of course, as Carl said, these are all BRE/Interpart part numbers and don't answer your original question ... but it's fun to get out the old catalogs and note the dog-eared pages from all that catalog surfing we did in the old days (before the internet!).

If I would have typed faster ... you would have had your answer...

BTW - and you might already know, but Mulholland was not the manufacturer's name, but the name coined by BRE for their suspension packages - named after the famous (infamous) Mulholland Drive just above Hollywood ...

And do you recall how you liked the Mulhollands? Harsh?

Who made the Mulholland shocks for them?

The Mulhollands were pretty firm - not as bad as adjustable Konis set to full firm though. The Mulholland package included stiffer springs that lowered nearly 2", along with bigger stabilizer bars. So, when you go from a nearly stock 240Z suspension to the full package - it was night and day and it's really hard (especially after 33 years) to try to separate the effect of the shocks as compared to the combination of the shocks and springs. I'll mention that today I run non-adjustable Tokico struts and Tokico springs and my impression is that the Tok set-up feels similar to the Mulholland set-up.

I just checked my latest Interpart catalog (1-1-74) and they have a number of pages describing all the Mulholland components but they don't specify any "% stiffer than stock" numbers nor do they specify who was the actual manufacturer. However, they show Mulholland shocks for about 25 different import/compact vehicles spread among the BMW, Chevy, Datsun, Ford, Mazda, Porsche, Toyota, and Volkswagen brands so I would imagine they sourced these with one of the big shock makers.

OK, I'd definitely like to find more info on these Mulholland struts, as I have a line on NOS Mulhollands, both 2351501 front and 2351502 rear.

Call it silly, but I'd really prefer to have set of non-gas charged struts to use with my Euro Stage 1 springs. These days, that means either Koni, or something NOS like these Mulhollands. So if any more of you really long-time Z people have any recollections you can share, I'd still love to hear it.
