5-speed in a low hump '67 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

NitroMike · 12-31-2005, 09:32 AM

Gentlemen, and Ladies, I'm new to the forum so please be gentle. I'm in the midst of installing a new Tremec 5-speed behind my 250. It's got a .64 rear 5th so it should work great with the 3.77 stock rear. Good gas mileage might be fun. My question revolves around the hole in the floor that I anticipate having to cut. Does anyone have the "high hump" bolt-in tunnel piece from a stock 4-speed. I'd like to get one to use as a starting point. Any other suggestions? Ideally, I'd like all of this to work with a factory type "high hump" carpet.
Thanks for any and all input.
