Posting more than I know
I have been looking for a booster for my '76 FJ40. What I've learned is that suddenly, in 2013, it is no longer possible to find readily available units that are rebuilt by the community at large, much less by the big remanufacturers. I have attempted therefore to revive this topic again, and to document, in one tidy place, what I've found out in the past 2 weeks looking for a '76 FJ40 Power Booster.
- '76, '77, '78, '79 and '80 boosters were the same on the FJ40. (not fact, but assumption from what I've read)
- OEM Boosters are no longer available. If you find a NOS (New, Old Stock), it would be worth a lot.
- SloCruisers doesn't have any more. He was given a batch of them a while back, and was able to attain the rebuild kits to fix them, sold them for a good profit.
- Booster Dewey (repair place in Oregon http://www.boosterdeweyexchange.com/) cannot get diaphrams anymore either. He is done with the 76-80 rebuilds unless someone starts making the diaphrams again. He can do '71-'75. Might be an alternative if the bolt pattern is the same, though they are not dual diaphram(? fact check me here)
- There are a few remaining rebuilds out there, but they are around $400 and up at SOR and other sites. If you want original OEM, then you will have to pay.
- Bolt spacing on the FJ40 OEM Booster for '76-'80 is 4" x 2 3/4" on center for the pedal-side bolts, and 3" x 1 3/4" for the Master Cylinder side bolts. The depth is approximately 7 1/4". Circumference is approximately 27 1/4" inches. Rod length to the center of the pin hole is between 13 1/4" and 12 3/4" depending on where you set the nut on the threaded rod.
- I have been able to find very little information showing the actual dimensions of the potential replacement boosters, including diameter, number of diaphrams (single or double), depth of the main cylinder, length of the rod, and bolt spacing. Aisin doesn't seem to publish their technical drawings and specs of their boosters anywhere. If you can find it, post it here, and I'll add it to this first post.
What *is* available is the following list of vehicles that I believe to be semi-bolt and play (may require modifying/ shortening the length of the rod on the Master Cylinder side, or modifying the length of the rod on the brake pedal side (by shortening the rod, or lengthening the threaded bracket that the brake pedal is pinned to). This list of vehicles appear to use the same bolt pattern as the OEM booster. Depth, rod length, diameter all seem to be different.

I hope this helps as a summary and repository for future needs. It is getting hard to find vehicles at the junk yards / pullApart places that are this old, so ordering remans is becoming the only way to find them.
Please write a post if you have further info on models, or see mistakes in my madness.
