I think it's time to replace rubber mount between transmission tail and crossmember. 50 years of oil leaking on it. All i see are ones with center stud. It doesn't look like mine has one. Is the stud removable?
That looks right but I have a th350. It lists your item for a 400. I'm not sure if hole spacing is the same on both.
I thought I bought them (I bought 2 or 3 of 'em) for a TH 350 & M21 as that would cover my cars & they were the same as TH 400. Now I need to check!
According to Anchor's site, 2378 is for TH350 & M21 (whew). 2288 is for TH400 & the pic of that one on their site shows the stud.
Now RA doesn't even list Anchor's part for TH350 or M21 & apparently has the wrong listing for TH400. Not the 1st time they've screwed up a listing although ofldd they'd go from correct to incorrect. They sent me 350 main bearings recently that were for a Chev. 267/302. I trust Anchor's site more than RA & I'm sure RA listed the 2378 for the TH350 & M21 when I bought them.
