I may be wrong but a planer blade would likely tear and chunk the rubber if it doesn't try tearing it from the bed.

So I went to the local rubber supply house and compared samples, nothing is a direct match. Closest material is available in the correct thickness but since I needed to machine the grooves I decided to purchase the next thickness up, unfortunately the guy cut my strip from the thinner material and I didn't realize until at home and ready to machine. That said I decided to test a few cuts and see if it would produce the desired look.

(Cut piece held behind original for comparison in each photo)

First pic is simply to see if I could cut the material and if it would be an acceptable look with shallow grooves.

Second pic is an attempt to cut TO the fiber (without cutting into the fiber and weakening, the material only has 2 plys of cloth, so not an exact material match)

A few pictures of one of the hangers I had kicking around from that warehouse with many others styles.
Rubber is only 3.5 inches long so wont help you.
Rivets same as used on many Mopar hangers, noteably regular E-bodies as seen in last picture....and NO,.. those aren't available.
If you give me some time till I get back there, I can get plenty of correct rubber size on big ol NOS truck hangers they have, that can be cut to size for your AAR hanger

The rubber on this NOS B-body hangers looks like a close match,... problem is it is only 2 inches wide, 10 inches long.

I have the angles and rivets covered (using the original "D" Tube rivets), the only thing missing is the rubber.

While the matting I've found doesn't have as many ply's of fabric, its new, pliable, fresh appearing, , , and certainly strong enough. I can make it appear very close to my original material, and I like that aspect. Seems "original" material can vary just looking at Floyd's example above Vs mine (AAR - T/A), and to a lesser degree mccanix. Not just the number of threaded ply's, but the back texture.

Floyd, do you know for sure yours are factory installed originals or parts counter hangers? With these hangers being AAR-T/A only, it would appear unlikely for such a short run of cars that our examples vary so much, carrying different rivet heads and the rubber has a texture on both the front and back.

I think I'll continue with the rubber I found and keep my eyes peeled for a closer replacement. Perhaps one day I'll run across an exact match and I could replace them once again. Until then, 99.9% (or greater) will never know the difference.

If anyone ever comes across a suitable match (or original piece in great shape), please PM me with details.

Material is very good, I think the 3" wide is the killer and during my salvage yard search I didn't run across any cars with a hanger that wide, though I will say there are no trucks in the yard I was at, so I don't know what they look like.

Thanks for all your help

Thought I'd provide an update . . .
Its been weeks, I ran into a ton of issues trying to cut the material clean.
I tried several thicker materials in a attempt to cut to the fiber and maintain the original thickness. Each attempt was extremely time consuming and resulted in failure for various reasons. Almost defeated I decided to go back to my original material choice and only make low cuts to give the appearance of the raised pattern.
Below are the results (original on the LH side and replacement piece on the RH side.

Are those original brackets? Where did you find the rivets?

Bracket on the left is original, one on the right I fabricated based on original examples. I had a set of aftermarket brackets and while functional there was so little right about them I just couldn't use them.

I went to the salvage yard and found an exhaust hanger on a C-body with the "D" rivets as my original, and reused the fasteners with some fancy engineering.

Now that I have a process I'll replace the rubber on the LH bracket as well.

Check McMaster Carr, they may have something similar and you don't have to order by the Semi Load.
