Inside the torque tube

The parts book photos shows the same illustration as the 1962 TSM, with six bolts at the front. I've only seen four bolt front flanges on 63-66 models, haven't been under a 62... has anyone? Do the 62s use a six bolt flange? Maybe 62 V-8 only? Just curious... I'm pretty certain the 63-66 V-8 uses the same four bolt flange as the 63-66 six cylinder models, possibly the same tube with just a different shaft inside. Length could be different though.

Not sure on the 62s.

Torque Tubes: Classic, Marlin, Ambassador:
1963-66 V8 largest diameter, non-replaceable center carrier bearing.
1964-66 232
1965-66 199 Different than 232 tubes in length, diameter, and rubber flange.

I don't know where that six bolt flange illustration comes from, or if it was ever used. Could have been a last minute production change, pre-production model(s) used for TSM photos may be the only one(s)to have it.

dterrilon... what does the "gasket" you bought look like? Is it square or rectangular, or is it round? The round one is made for the earlier cars.

But let's take it from the top...  The flange that bolts to the transmission "floats" on the end of the tube, it's not welded to it. IIRC the rubber is fused to the inside of the flange. The tube itself is "belled" on the end so the flange won't pull off. The rubber is actually on both sides of that bell end -- the gasket should have a groove in it that the bell fits in. With the rubber scraped off as you indicate you've done, the flange should easily move on the tube, but won't come off.

At the factory the end of the torque tube is attached as a unit. You can see the welded joint about 6" back from the end. That end is assembled with the rubber fused on, then slipped on the tube and welded on. Galvin's makes a replacement tube (you send yours as a core) with new rubber.

Now, you MAY (should, I'd think) be able to use the older style -- which might be what you have. As long as it fits the end of the tube (the belled end of the tube) it should work. You will have to trim the round sides square to fit just inside the flange. The flange will hold the rubber in shape as it is sandwiched between the trans and the flange. Don't trim the rubber back and further than you have to though. You want it to be a snug fit inside the cavity. 

i'll second that... the TSM is pretty much required reading on a 60 year old chunk or iron...

The chap who sells the trunnion for the earlier cars

told me it won't fit my 63, and I should buy one from Galvins.
Galvin sell the trunnion alone, or the recon unit.

If the trunnion is essentially a sandwich, hard to see why I would need to buy the whole tube.
