Here is our Heavy Duty replacement Engine Crossmember for the early model GM Trucks (designed off a 1971 model). It features a full replacement of the factory crossmember and has adjustability front-to-back for engine placement. LS Specific integrated motor mounts utilizing poly bushings included! Due to the design of the integrated motor mounts, we also leave room for the factory low-mount AC compressor! Possible slight clearancing of the frame rail may be needed, but on our prototypes it was not required at all - however you will need to purchase some tight right-angle hose adapters for use at the compressor fittings. There is a drop-out tubular center section for oil pan access.
This item is "Make to Order", and can take anywhere from 1-3 weeks to fabricate before shipping, depending on our current workload!
