A body 4 speed shifter hump?

That fiberglass hump is sturdier than you think. There are bonding agents on the market that will bond it so good, it will never come out.
can confirm. have the 'glass hump in current project and have had one in two others. it's le beouf.

i'll echo what other have said above in that the pre 67 stuff is different. however, with your metal working skills i don't doubt that you could start with a 67+ hump or stab in part and fab out the rest. but that's a buncha work for something that is somewhat easy to track down.
