Wheels : Ford rims have the 4.5 inch ( 4 and one half ) lug stud spacing size you'll need to fit AMC drums....BUT.....sometimes the center hole where the FRONT hub on the AMC goes thru the Ford rim is too tight, and you have to file out the hole some ( on the Ford rim ). not a problem on rear drums with no bearing hub, but on the fronts, you'll need to check it before you buy the Ford rim. You'll also want to check "offset "...that is, how deep the lug nut area is from the front edge of rim depth-wise, so that a Ford rim that might have the lugs out front, won't rub any suspension parts. To do this, lay a flat 14 inch item across the rim lips, not touching the rubber tire. measure between the inside ( closest) point to the lug nut hole. That is your "offset ", roughly . Not sure if it's measured from the front side, or the rear, but make sure you measure BOTH AMC and Ford rims to get it within 1/2 inch or so. Plastic Parts : Don't have any spares at this time, I "Might" have the shifter ball and socket for the 3-speed shifter, but would have to check. 68 Javelin clip : is this a flat piece of plastic that slides over a peg welded into the car body? If so, they can sometimes be found at Van and Customizing interior places, as I've found some locally that will fit my Pacer wagon roof. Might want to check with body repair shops, too, see if they have a source. [Non-text portions of this message have been removed]
