Don't know if the origional older gentelman is still the owner. I met him at his house to talk about buying an A Body 8 3/4 Housing from him.
He was / is a nice guy. I let him drive my Dart around the block, he said he had one in his past.
As for products, I can't say. I believe he has his work done at a speed shop in Greeley, CO. At least that is where he had me drop off an E body housing I sold him.
I saw a Craig's list ad for a complete rear end in CA a few years ago, the seller said it was from Mopar Madness in CO.
The seller wanted way too much IMHO.
good luck.
