Lozer Posted May 30, 2017 Report Share Posted May 30, 2017 So I have a good 71b 5 speed and a 71c with a wasted 2nd gear synchro and possibly gear. My 510 has a Kade in it. I'm wondering if I can swap the cases to keep the angle and length of the 71c Quote Link to comment
Three B's Racing Posted June 1, 2017 Report Share Posted June 1, 2017 Should be able to swap the bellhousings but may find your countershafts front bearing on the 71b smaller is diameter and will have to change it to a 62mm. Quote Link to comment
Crashtd420 Posted June 1, 2017 Report Share Posted June 1, 2017 I think have seen some write up about doing what your saying.... I do remember reading there are some other diameters that need to be opened up too.. I re-read what you posted Personally i am a little confused .. are you trying to just swap the internals?

Crashtd420 Posted June 1, 2017 Report Share Posted June 1, 2017 The little bit I read sounds like the tail section of the 2 transmissions might be different... They say you can swap the bellhousings from one to the other with minor mods... The first thing I would do is measure the length of both tail sections... Posting some pics and a little extra info might help... For instance pics of the bellhousings.. And what's the vehicle... And I know the 71b came in 2 different length and 2 different bellhousings.... Not sure if there is more then one variation of the 71c Quote Link to comment
Crashtd420 Posted June 1, 2017 Report Share Posted June 1, 2017 Me again.... so I get bored at work watching my machine run... and I looked up a 71c transmission and it looks like you can get a rebuild kit for around $100... Gives your bearings and syncros... If you willing to go through the labor and hasle of swapping cases which may or may not give you the desired end result.. It Might be a lot easier to rebuild what you have.... obviously depends on what is truely wrong with the transmission... Quote Link to comment
Three B's Racing Posted June 2, 2017 Report Share Posted June 2, 2017 I just rebuilt a 71C from a RWD SR20DE S14. Easy to do, just take lots of pictures and search Youtube for FS5W71C rebuild. 1 Quote Link to comment
datzenmike Posted June 2, 2017 Report Share Posted June 2, 2017 The 71B is different length so the main shaft will stick out the back if the C is from a truck and will be too short if from an sx. The bell housing isn't actually removable. The bell is an integral part of the front case that contains the first 4 forward gears. 1 Quote Link to comment
