[the shadow]

I am looking at buying a used cobra mrkII chassis and wondered if any of the recent FF chassis up grades can be applied to the older chassis? or if any of you can suggest an up grade to the chassis. the one I am most interested in but have not seen in person yet is a mrk II it has all '88 donor car parts, 306 efi/5 speed (engine & trans are recently fresh).
things I would do to it are:
5 lug rear axle's & new 5 lug drums
5 lug front rotors & etter brakes
lose the original EFI in favor of a carbed manifold & msd set up
5 lug 15" halibrand style FFR wheels
3.55 rear gears
adj upper & lower tubular rear control arms

I keep hearing about newer cars having lowered floor pans & larger foot box's, are the mrk II's cramped that much that the need more foot room. are there any chassis mods that would make a great differance that you gus can suggest?
