TCI makes an excellent product, and if you are going with a small block it is a very good choice. In fact, I was literally on the phone with them (by the way I can refer you to an excellent guy out of Seattle who can get you the kit for a great price) with my credit card info when I found out that my engine choice (351C) was not compatible. Anyways, I ended up NOT going with the TCI, mostly for that reason.
This turned me to Rod & Custom. They make a crossmember specifically for the 351, so I went with them. As far as the kit quality: Excellent. I am extremely happy. Honestly, if I was going to do it again, and build a 5.0 60's Mustang I would call Rod & Custom in a heartbeat. Basically, everything they give you is pretty much what you get with the TCI kit. HOWEVER, I do believe a little more thought was put into this kit. Over all it does not seem as flashy, but I think it might be a better kit over-all. For one things, the guys who designed it have been around a long time, where TCI is a bit of a new-comer to this market. These guys do one thing only, which is this type of
suspension.
Also the RC kit includes all your linkage for steering- something TCI did not include, or at least in the package I looked at. Cost was about neck-and-neck.
TCI makes it easy to install, but R & C makes it easier, IMHO. With TCI you need to box your frame rails in yourself, and them trim to get it to fit. R&C comes with the boxing already welded to the crossmember. Much easier to install, and you still get the same boxing. Also, the welds on the crossmember are second to none.
Anyways, I don't get a referral perk or anything, I'm just passing on my experience. We just cut out the shock towers on mine today, and Thurs we will most likely weld it in.
I think TCI makes a great kit, but I would seriously check out the Rod & Custom stuff too. If your looking for flashy documentation, a pretty website, and cool stickers you will be disappointed. TCI does have that. Call the guys at RC though and just
talk to them about it. They will talk to you for hours. When I called TCI they didn't have much to say.
Just my $.02! I will be following. Also follow my thread- you will see everything in action over the next week or two.
