My '67 Valiant 100 Big Block 4 Speed Restoration

I be wiping them cylinder walls down with WD-40 and fresh paper towels if I were you.

A good rust free floor in this part of the country will be near impossible to find. Shipping one in from the west will be expensive too. I have seen the a-body full floors up at Chryslers at Carlisle a few times. Now that new floors can be had I would bet the original floors would be cheaper. Crackedback might be able to find you one and cut it down the middle of the trans tunnel to save on shipping.
