I used the TCI Mustang 2 setup in my 55. It has worked out very good for me.The truck rides and handles just great.It all depends on what you want your finished truck to be. The directions were pretty good that came with the front end. I did have to make one phone call to them concerning the power steering pump.They use a Thunderbird rack and pinion setup and if you use a GM Power steering pump,you have to reduce the pressure.Ford units use approx. 700 to 800PSI,where as GM pumps put out 1200 to 1300 PSI. I got a pressure reduction valve to put in my GM pump. As with any modification you have to measure carefully,I measured mine about 6 times before I welded the crossmember inJust to be sure everything was lined up correctly.Of course I pulled the front clip off of the truck and pulled the engine out,to do the job.There is no comparison as to the ride and handling,between the stock setup and the M2 frontends.
