1. when im driving my 1972 c-10 with a 250 three speed the shifter on the column shakes at high rpm is this caused because i dont have a tranny crossmember. if so where can i pick one up?

2. will langdons headers get in the way of my shift or clutch linkage?

3. i want to put an oil filter relocation kit in. where would be the best place not in the way or hard to get at?
