Rear crossmember exhaust hanger?

[mtgibby]

The previous owner replaced the rear crossmember before the chassis was restored. There are no holes in the crossmember for the rear exhaust hangers.

Using the authenticity manual, I see the hangers are bolted onto the front of the tube, near the outboard sides.

Question: do the bolt holes go all the way through or do I just drill and tap and use a short bolt?

They do not go all the way through, although plenty of folks have drilled completely through and used a long 5/16" bolt & nut.

But to do it correct, drill a hole slightly smaller than 5/16" in the proper locations at the front of the tube (only), then use a self-starting 5/16" bolt with a flat washer under its head.

Don't tighten it too much....there's really no 'meat' in that tube!

Thanks! The pictures in the authenticity manual didn't show the mount very clearly, and one picture looked like the bolt passed through the tube.

I will follow your suggestion for mounting the hangers!
