Hi Rich,
The parts needed for the conversion are the following;
1. 2.8 V6 from a Mustang/Mustang II/Capri/Capri II, years 1974-1979, or a Ranger/Bronco II, years 1983-1985.
2. The preferred T5 transmission for this swap, is from a 1996 and later, Mustang with the 3.8 V6 engine. A T5 from a 5.0 Mustang/Capri V8, years 1979-1993 will also work. The T54 unit from a four cylinder car will work, but is not the best choice, because the gear ratios aren't ideal for this swap.
3. The driveshaft comes from a 1983-1986 Thunderbird, with the 3.6 V6 engine. It has the correct yoke to fit the T5 transmission, yet is small enough in diameter to fit the narrow Alpine drive shaft tunnel.
4. If you want an upgrade to the rear end, the Mustang II 8", will have the same bolt pattern as your Alpine. The stock Alpine rear can be strengthened, by replacing the stock, butter soft, axle woodruff keys. Also the ring gear bolts need to be checked for tightness and Loctited, so they don't loosen again. It will handle quite a bit of power, but if you are planning on driving it hard, I would suggest going with the 8"
5. A heavy duty three core radiator. You can have the stock core replaced at a radiator shop. The location of the intake and outlet nipples will have to be changed, but the radiator shop can accommodate this.
6. Of course, you don't need a kit, but it facilitates the conversion.
These are the parts you'll need for placing the engine in the car. There are other smaller parts you'll need too, but these are the most important to begin with.

p.s. I may have forgotten something, but I'm a forgetful old man, so you'll need to forgive me.
I'm just thinking out loud..... not ready to move on it yet, but:
Does anyone have a detailed list of the components and their applications for the V6 conversion?
What model and years for the engine, transmission, rear member?
Which of those components need to modified?
Driveshaft?
Axles?
Rear brakes?
I was thinking of having my Dad acquire the components back in the midwest, and would like to give him a list of what to start looking for.
With all of that, since my care has original wire wheels, I'm sure it'd be best to convert to lugs.
