So I removed my 4 speed transmission and transfer case from my 1976 Fj40 today to get it ready to send to Valley hybrids to get rebuilt. There was a lang propeller looking attachment attached to the back of the transfer case that then bolted to the frame. My guess it was an aftermarket part to hold the trans and transfer case as the PO removed the 2F and installed a SBC motor. Is the only thing holding the trans and transfer case up is the 2 rear engine mount brackets? Do I just remove this bracket and purchase an original cover plate?
