Chassis swap questions for two different cars

[Monty]

1)  Built this kit as a kid decades ago, and would like to eventually take another shot at it.

Among other things, I'd like to replace its promo-like chassis with something more detailed, such as the one from AMT's '65 Galaxie.  I looked into this a number of years ago because the poseable steering intrigued me, but the Merc has a longer wheel base.  How would you modify the Galaxie's chassis to make up the difference?

2) Has anybody ever used an MPC C3 ('68-'82 Corvette) chassis to upgrade the AMT '63 Corvette's 2-wire-axle unit?  I prefer them to the Revellogram units because of the poseable steering and the IRS setup.

I used the '65 chassis under this custom I did a couple decades ago. IIRC, I only had to move the rear suspension back a touch. No cutting was involved. I did cut out the molded in exhaust, patched the floor and used solder to make a new exhaust though..

The chassis from the AMT 1960 Ford is an excellent choice, very well detailed. I used it under a ‘64 Merc I built a few years ago. Very little modifications to make it fit.

Thanks.  I figured it might be, but I'm looking for chassis designed with poseable steering, which I know the '65 Galaxie has.  OTOH, that '60 Ford might be worth getting for what I assume is a far better engine than either of the other kits.  Hmmm.

The fact that you did this decades ago and it turned out exceptionally well won't come as a surprise to anybody on here. 

My stuff's in storage several states away so I don't have the kits here to measure, but I'd swear the Merc's wheelbase was easily 6 scale inches longer, hence the question.

Thanks.

It's just 4 inches longer Monty. I just looked it up. Really, All I had to do for the wheelbase was move the rear axle and control arms back a bit. The tires still fit in the wheel houses without touching them.

The '65 Galaxie chassis is a more accurate choice for the '66 Merc. The frame from the '60 Galaxie ('57 to '64) is a completely different configuration than the '65 and up Fords.

Looks like the Galaxie chassis will be the best choice here.

Still hoping for some input on the MPC chassis as an upgrade for the AMT '63 'Vette.  Pics would be great if ya have 'em.
