Dirty Dingo adjustable transmission cross member bolts into 2WD 1963-1987(91) C10 C20 Truck's, Blazer's, and Suburban's. Certain square body models continued to be manufactured up to 1991 such as the SUV and were renamed as the R/V series instead of the C/K series as they were produced alongside the OBS GMT400 models. This will still fit the R10 and R20 series trucks. In most cases, this cross member will bolt to the frame using existing transmission mounting holes.

This adjustable cross member will allow you to run a Powerglide, TH350, TH400, 700R4, 4L60, 4L65, 4L70, 4L75, 4L80, 6L80, and 6L90 and adjust the cross member without drilling any new holes into your frame. This is designed for lifted or lowered trucks and will retain the factory transmission angle for proper driveshaft alignment. CNC bent 1 3/4" diameter tubing with 1/4" plates that will clear long tube headers and exhaust up to 4" in diameter. The cross member is above the frame rails and will clear when laying the frame on the pavement. Includes grade-8 bolts, washers, and Teflon locking nuts for installation. They were welded and cooled in a custom fixture for a precision fit.
