upgrading 66 GT With 74 Valiant Front end?

My main question will the 74 Valiant hardware (front suspension-arms, steering linkage) fit the 66 GT frame. the donor car has double master cyc I'm pulling it. The rear end- pulling it out.. Portioning Valve-pulling it with the brake lines- which I going to keep as a pattern for making up new lines..

LOL! I can't answer for sure if the drag link/idler/pitman pieces will all go in, but the upper/lower control arms, spindles, brakes, etc should all go in without issue.

You'll still need to use the early A pitman, idler arm and centerlink as they are unique to the early A. UCAs, disc spindle, LCAs, torsion bars, rear end, etc bolt right on. If your early A has a sway bar, re-use your LCAs and swap the disc spindles from side to side so there won't be any interference with the sway bar. Am doing a similar swap on both my 65 Darts.
