Should the exhaust bracket that holds the exhaust system under the gearbox have rubber grommets or spacers where it bolts to the frame?
I noticed such a rubber spacer in the photobucket pics that Alwallace linked yesterday in his "opinions wanted" post.
I didn't see any when I took mine apart, but I can see where it might make sense to have them.
Thanks,
John

Yup, should be nesting grommets there. But they don't hold up so well, so they are frequently missing.

Thanks! Another bit of rubber to find.

Available from moss or TRF, I forget where I got mine.

During my restoration from 1987 to 1990, I used a support that is sold for a TR4. No rubber needed.

I used the TR4 solid piece too. Bolt on even on my early 3...very solid

I gave up on the solid bracket on my TR4 and substituted a modern "generic" bracket with a molded rubber mount. This eliminated the resonance one normally feels at 2700-3000 rpm.

You can also find these grommets as hardware store items.

Against the grain of much of the commentary above: I don't see anything wrong with the TR3 bracket you're asking about. Things are certainly congested and hard to get at in that area, but this is pretty much a standard state of affairs for TR3s. And the TR3 bracket does provide spring tension at that point, which protects a bit against some mechanical rattles which can develop around that zone.

Thanks everybody. This discussion gives me a much clearer idea of how the exhaust is suppoed to be supported.
This part of my car was a dark greasy place filled with road debris that I didn't want to visit, but I did and I found a broken tranny mount and a half disconnected exhaust hanger. I'm glad to get that all fixed.
