Have a lead on a Dana-Spicer 3053A 5-speed manual transmission for cheap. Current owner says its an overdrive, curious to know a couple of things about it: 1) Did these ever come behind the SB, BB or diesels? 2) If not, can they use the SM465 or SM420 bellhousing? I'd be bolting to a 350 or 6.5NA Diesel 3) what ratio is the OD? 4) what divorced T-cases were used behind them in 4x4's?
