Gratiot Auto Supply
 

Pronounced, Grash-it , was our go to speed shop back in the day, it seemed like it was all expensive, lol. (Circa,1977)
If you want a few more from the catalog, I can do a few more
looks like Vaughn has some aftermarket’s parts

I had that one. I wish I hadn't tossed all of my old catalogs in the trash many years ago. I ordered a set of muffler inserts for my chrome side pipes from them about the time they were going out of business and I never got them.

Gratiot was our go-to place then Ramchargers once Gratiot went bankrupt. Two problems buying from Gratiot:

1. If you ended-up with the wrong part, they didn't do refunds....store credit only. Even if their counter guy looked up the part!
2. Buying "bargain" Holley carbs was great until you try to buy a rebuild kit at some point only to find nobody can ID the list#. Holley would offload bastard production runs of carbs to Gratiot. You could eventually match up another 4150 kit but was a PITA for the parts store folks.

I ordered 2 polished stainless Bolas from Ramchargers, the guy sold them to me for cost. I didn’t know that at the time, still on my TA, best mufflers I ever bought.
