alrighty, so im squaring everything up before i buy to much or to little parts and come to a problem.

im getting a soarer r154 from sf and im getting the 1peice aluminum driveshaft from driftmotion. my question is, will this driveshaft fit my stock auto diff, or do i need the 3 to 4 bolt adapter to make it work? im very confused

 

Any specific reason you are going with DM driveshaft? There are cheaper and easier ways.

 

only reason is because im ordering everything else i need from them.
ie: the r154 manual swap parts

should i just get a r154 front half and then could i use my stock auto rear half that goes into the pumpkin? idk, this is the only part of the swap im confused on.
