518 Crossmember Kit - 67-75 Dodge Plymouth A-Body
Engineered to facilitate installing a Chrysler 518 overdrive automatic transmission into a Dodge/Plymouth Mopar A Body car. Requires additional fabrication and welding.
Made from 3/16 thick steel, this replaces the factory transmission cross-member transmission mount. Provides the additional height and width required to for the 518 Transmission. Additional clearance may be required including cutting the factory crossmember for the transmission tail-shaft and the speedometer or VSS cable/sensor. The factory floor remains in the original location. Requires welding in the replacement USCT transmission mount tab. The tab is designed to accept the common GM stud-type transmission mount (#10473052) . The USCT cross-member is a fully boxed section, engineered to provide the structural integrity that would be lost by removing the factory cross-member. The kit includes the cross-member, lower transmission mount tab, Grade 8 mounting hardware and instructions for installation. The GM style insulator (#10473052) is not included and is available in almost every auto parts store.
The components are factory jig welded, ready for installation. Requires fabrication and welding to install.
