1968 thru 1979 C-3 Corvette cross member for Th-700R4
(This cross member fits all corvettes that have a removable cross member, doesn't fit 4-speed manual models)
Our 1.5 O.D. heavy wall .188 thick D.O.M. tubing custom built cross member allows for the direct bolt of a Th-700R4, using the stock frame holes, brackets and bolts. The Th-700R4 is 3.13" longer than your typical short tail housing Th-350 and 2.50 longer than a typical short tail housing Th-400. The drive shaft will need to be shortened by this amount, which positions the U joint further towards the rear of the car. This new U joint position interferes with the emergency brake cable. Incorporated into our design is a bracket to reposition the emergency brake cable so it will clear the newly positioned U joint. Just remove the nylon guide wheel from the old cross member, using the same hardware, install it onto the new cross member. We designed very high arches into the cross member tube for maximum clearance for custom exhaust. In fact, our cross member is higher the foot wells in the floor pan of the body, which will allow maximum clearance for exhaust tubing. Since they no longer have to route through the cross member, very large diameter exhaust tubes can be used.
Crossmembers come in RAW STEEL
