BRACKET,MUFFLER 74 T140 - Replaces 83-7582 83-7021 83-7022 (with 10mm thick spacer)
Rear muffler mounting bracket for the 1974 750 twin, with a 10mm spacer, replacing the earlier 83-7582/83-7021/83-7022 setup.
This is the muffler bracket used on the 750 twins for the 1974 model year, listed in the parts book under EXHAUST PIPES AND MUFFLERS. It's the piece that ties the rear silencer to the frame, taking the place of the earlier setup used on 83-7582, 83-7021, and 83-7022, and it comes with a 10mm thick spacer to suit the revised mounting.

If you're working from an older parts book and see one of those earlier numbers called out for your bike, this bracket is the replacement — the catalogs list it as a direct supersession. It shows up across our records for the '73-'74 span of the 750 twins, so if you've got a 74 T140 this is worth checking against your own parts book before ordering.
It's a straightforward mounting bracket, not something with moving parts, but exhaust hangers do take a fair bit of vibration over the years, so cracked or elongated mounting holes are common enough on old ones. Worth a look at yours before you decide whether you need a fresh one.
