LJ20 transfer case mounts (cross-compatibility w/LJ50 or LJ80?)

I'm in the process of refurbishing my '72 LJ20 transfer case. The gear oil is very clean (yay!), but it's leaky. I'll be replacing the seals; I'm talking with a local bearing place on Monday to get the proper seals.

As I was taking it apart to clean it up, the rubber on a couple of the transfer case mounts delaminated from the steel. I'm finding some LJ50/LJ80 mounts on eBay that look like mine, and wondered if the mounts were the same as the LJ20s. Can anyone confirm?

Also, my lower shift boot is torn. I took measurements on the shift tower, and am curious if the lower shift boot from a Samurai transfer case will fit.

Thanks!
Craig

The LJ50/80 transfer case mounts will not work; the base is longer than the LJ20 mount.

I'm not sure if a Samurai boot will fit for that lower boot. I can still order the boot new though. It runs about $15.

Thank you for confirming, Steve. I'll add the LJ20 lower shift boot to my order list from you. I'll shoot you a PM in the very near future.

Thanks,
Craig

What's the center-to-center hole measurement on the LJ80 transfer case mounts?

From a seller of LJ80 mounts on eBay... (for future search purposes)

These mounts measure 106 mm approx between the holes

I think that's a little short. I measured one this morning and it is about 113mm from center to center, or 4.45".

Looks like the seller was measuring the actual distance between the holes, and not the center to center distance. Assuming 8mm dia bolts, that'd work out about right.

Thanks for the additional clarification, Tom. Much appreciated.
