I have a '85 ex-Army Blazer and want to install a 5-speed manual transmission. Is there a 5-speed that fits into the 6.2 Diesel Blazer, without any problems with the transfer case? also I would need the whole clutch assembly. I need to know which Truck was build with a 5-speed (or at least a 4-speed) that is transferable into the 6.2Blazer. any hint would be appreciated!!! thanks for your help!!!!
