I would use Darkhorse if I was going to do it again. Plenty of the CA guys on VMF used them and I have never heard a complaint.

Regarding Forte Parts...CHPSK8, consider yourself lucky. Don't use Forte Parts.
Here's my cut and paste I use whenever his name comes up on forums...
I bought my TKO600 kit from Mike Forte himself and had to call him back to tell him the x-member didn't fit. I was surprised to immediately detect an attitude, b/c during my order phone call, he was a great guy and we spent 15 minutes just BS-ing about my car and a vintage racer we both knew. So I told him if he doesn't believe me, I'll e-mail some photos.

I did e-mail photos and he e-mailed back said "Fine, send it back, but store credit only or there's a 15% restocking fee on refunds." I balked over that, saying would you charge that if you sent me a Chevy part that didn't fit and I had to return it? I don't see the difference". But anyway, I did send it back.
After about a month or so I realized I never heard from him. I called looking for the refund I never got, and he says "how do I know you sent it back?" Kind of shocked, I told him I'd dig up the tracking number since I sent it from work. So I did find the UPS Tracking number, and sent it to him. But he e-mails back "that just proves you sent me SOMETHING. How do I know you didn't send me an empty box?" (I just spend $3k with him and he's screwing me for $125 return?) I couldn't believe it, this is supposedly a big name in the cobra kit car business, and I figured since I'm in NY I'd use an MA guy versus someone in CA like D&D or DarkHorse. Big Mistake.
So I called him and after a long argument getting nowhere, he finally says "well, whether you sent it back or not, I sold you a "kit" for that price. The crossmember was thrown in free of charge, so there will be no refund". (You can't make this up, right?) I said to him "then send it back, I'll sell it on ebay for the $125 you normally sell it for" and after a long pause, he says "NO. I still think you sent me an empty box. I've got a business to run, not a charity- have nice life."
So there is my Mike Forte story. I still have the e-mails. I've seen enough vendor disputes on other threads to know there is usually two sides to a story, but in this case there really isn't. Does he really think I bothered to mail him an empty box? Or that the xmember was part of a kit, so there's no credit for returning it? And remember, that free/no-value bit is after he WAS going to give me store credit or ding me 15% restocking it. Come on.
I've warned several folks away from him since, both in person and on other web boards, and I know he's lost far more than the $125 he screwed me on. On my $45k Mach 1 restoration, $125 is not even worth talking about. But if someone in the future searches on his name here on Stangnet before they decide where to spend $3k+ on a Tremec swap, he may lose another sale. Karma's a bitch that way.
