rb crossmembers and mounts

[JedC]

I was wondering if anybody could tell me the differences between rb20, rb25 and rb26 mounts. Are the actual rubber mounts the same and just the brackets different? Do the mckinney mounts replace the brackets or the rubber mounts and what other mount pieces do you use with them?

Let's say I had an rb20 crossmember and mounts and had an rb25 engine. Would the rb20 mounts fit or would I have to use rb25 mounts? I'm guessing as long as it's an rb rwd crossmember it doesn't matter right.

Thanks a lot guys, Jed

The R32 and R33 crossmembers are different. I have a RB25 I am trying to use the R32 crossmember and motor mounts on. Until then, I don't know if it is possibly and no one who responded to my thread on this board or the other boards knew the answer either.
