Home built rack and pinion+ coilover build.

Kim, the problem is the length of the Mopar lower control arm demands a long tie rod to keep the wheels parallel throughout travel. (The original suspension that the Pinto had had short lower control arms, so the overall width was narrower in stock use.)
If the tie rod is too short, the wheels pull in whenever the suspension moves either up or down. If it is too long, they will toe out. So the problem then becomes the distance between the inner tie rod ends. On the Mopar early A, that length needs to be about 21 inch. I spotted a reference on another web site to a shop called THE RACE SHOP in Seymour Wis. They have narrowed racks in the past and I am going to see if they still do. The price back in 2008 was $150, hope it is still under $200.
By shortening the rack the exact needed amount, then everything SHOULD line up. I am still hoping someone will post the specs for stock disc brake rotor to Zerk length, which will tell me how well this whole deal will fit with a conversion to 73 and up factory discs, which a lot of guys would like to do.
