They fit like a glove!

I went with the Dynomax 17375 pieced together from RockAuto.
That gave me te chance to use Walker 20" Super Turbo mufflers instead of the Ultra Flow SS. The sound is probably sweeter with the ultra flow, but I wanted it as quiet as possible.

Naturally, I had to modify the pipes where they normally connect to the dual cats of the 94-96 (and of course modify the crossmember), but other than that it was a perfect fit for my 77 box caprice.

Thanks!
I used a universal hanger welded to the lower muffler flange.
Then I bent it and bolted it to the body. I could reuse one of the bolt holes from the original mount, and had to drill a new one on the other side.

Not by the car until Sunday, but I'll take a picture if I remember.

Got a better picture today.

I reused the parking brake cable mount hole on the driver side, and drilled a new one on the passenger side.
