Are the 92s the ones with the aluminum body and the plastic top? Leaking at the seals between the plastic & the aluminum? The early 2 piece masters worked pretty well, but they have probably been "upgraded" to the newer seals that are not worth two hoots. It seems there was about a 3-4 year window where the masters didn't seal well. earlier or later ones seemed a bit better.

I think the older one piece cast masters will bolt up to the booster, you just need to get one with the correct number of mounting bolts (2 or 4). I'm thinking the early 80s trucks have what your probably looking for.

I'm also having a lot less trouble with the mid 90s Dakota masters, they seem to seal pretty good. Gene
