Can the c4 tranny crossmember be easily modified to fit the c6? i'm kinda on a budget, and i am going to have to have the driveshaft shortened. i located a 390 gt, with mercury valvecovers in an old ford ranger in a junk yard. it has the c6, and a 9" rear that's the same width as my 67's 8", for around $300.:eek2:
