I recently have come across a 4 speed for $200. It is a working e body a-833 4 speed. I currently have a 3 speed that is mated to my 318. My question is, can I just swap all the components on my 3 speed, onto my 4 speed? The guy is giving my a small block bellhousing. Will the clutch and pressure plate be the same along with all the rods fpr the swap, or do I have to buy a new clutch and pressure plate? The clutch in the 3 speed is brand new. Will I need to shorten my driveshaft? I am not real good with transmission stuff so any help would be appreciated.
