Just Another Damned Z Car Project Thread

It doesn’t ruin any original parts

Well in the 'nothing can be too easy on this car' column, I contacted Power Brake Exchange to buy a 79-81 power brake booster and they don't have one even though their website says they have one in both locations. Dude was apologetic but says "our website hasn't been right in a decade or so."

I put a WTB on Facebook Datsun Parts and Needs but if you have one, let me know!

82 won't work? I seem to remember something said about the bolt pattern. Not sure though.

I don't know David. I heard 79-81...

Yeah, seems I remember something about not having to drill new mount holes on the 79-81. Bolt pattern was bigger on 82-83.

You may have seen this on eBay already. If not I found this. Could be a good candidate for a rebuild.

[conedodger]

Thanks Yarb, 

I hear though that it isn't actually a 'bolt up' and I'm already building adapters and such so I think I'll just rebuild mine... Unless you have information that is contrary to that???

[Yarb]

Definitely 79-81, Bolt pattern 180 degrees out on 82-83. I purchased mine from Power Brake about 6 months ago.

Did a couple stops yesterday. I went to AutoZone and O'Reilly's. Both list the 79-81 online but neither can get it according to their counter staff. Motorsports Auto lists it and doesn't say it isn't available but they want a $300 core and I don't have one to send, though I can get a very rusty one on ebay for $60 shipped. 

Yarb, are you getting 'considerable' assist? Something you notice?

[Yarb]

Ok, Here ate some pics of my 1978 OEM booster. 
The dimensions are:

Top horizontal stud dimension left to right. center to center.  3 5/16”

Vertical center to center 2 3/4”

Overall booster diameter 9”

Hope this helps. Let me know if there is anything else You need.

[conedodger]

I will check it when I get home. Thanks!
