Designed with G-Force to accommodate a 4L80 into a 64-67 GM A body frame that has the 4 hole cross member mount on the original frame. This design utilizes a mounting platform bolted to the existing frame holes and the factory vertical plate welded to the upper and lower frame channels at the mid body bushing area. Due to the much longer size and mounting location of a 4L80 relative to the factory 4 hole crossmember mount, use of only the 4 holes in the existing frame resulted in unacceptable deflection of the crossmember. By locating the mounting tabs of the crossmember further rearward deflection is no longer a concern. Installed on a 66 Chevelle to verify fitment. $299/OBO
