I bought a TCI Must II IFS from a vendor & installed it in a 48 GMC. I also got a power R&P, but do not know if it is a Must II or a T-bird R&P. Does anyone know how to tell the differance between the two?

Best to check with your vendor. If it's the 59" wide kit, it's probably a T'Bird R&P. That's what I got with my TCI MII kit (for a 55 Chevy truck).

Each has a different ratio, but I do not know what the ratios are.

I just went through this and learned that there are 3 ratios. 3 turns, 2.5 turns, and 2.25 sport steering. 3 is for stock application. I chose the 3 since hot rod steering seems sensitive anyway. There is also two different width mounting patterns. one for p/s and one for man. steering. Local auto parts should show this on a 1990 Mustang w/V8 look up. Hope this helps.

Thanks....it did help.

Original Mustang 2 racks were 15-1/2" center to center on the rack bushings (if they are a two bolt mount, some were 3). The T bird rack is 16". The T bird rack also uses 14mm and 16mm fittings that seal on a crush washer(they will have a machined surface at the top of the threads.)

Early Mustang 2 racks used a 9/16 and 5/8 inverted flare fittings with a small flare adapter that seats down in below the threads.

Most guys are using the Thunderbird rack now because the supply of Mustang 2 racks have dried up.

Don,
Now that you have some answers to your original question I hope you don't mind if I go off topic.
I like the bed on your truck, it is very similar to what I want to do on my custom 39 Plymouth truck. Is this a completely custom bed or did you start with something stock and do some modifications? If you started with a stock bed what did you use? Right now I'm thinking early 50's Studebaker as a starting point but that really doesn'r simplify my parts search much! If there is something newer and more readily available I would love to know about it.

I started w/a Chevy bed. It took me 3 mos working every day to modify it & add Caddy fins.
