Re: Bolt in high hump.

Believe this should be in the WTB Parts or the classified section but you need to be a paid member to post there.

Re: Bolt in high hump.

I bought one from AMD. Seems like good quality.

Re: Bolt in high hump.

beware: there are two different bolt-in high humps. one for a 2wd (no transfer case) and one for 4wd.

I have a new, in the box, AMD hump for the 2wd with no shifter hole. PM me if interested.

What's the difference in the 81-87 floor?

Sorry but I don't know. I'm using a 4x4 bolt in hump in a 1975 GMC Sierra. The truck is on a Roadster Shop SPEC chassis and requires the additional clearance the 4X4 hump provides for the LS/4L80e.

Excellent question as AMD only shows bolt-in high hump options up to 1980 year model.

Their complete floor pan only fits 1973-80 as well ...
