The car 71C is about 34" long, the truck 71C is about 30"? This is +- I haven't measured one myself.


You can machine a 71B case for the 62mm counter bearing, or just pull the 62mm bearing off the 71C and put a 56mm bearing for a 71B on it. There's more...


The first/second shift rod hole in the 71B case need to be enlarged from 14mm to 16mm

The inside of the 71B case needs to be machined around the counter bearing




So it looks like this...




The 71C uses wider gears and they stick out farther. If you don't machine the case and you tighten the case on you won't be able to turn it.



The change from 71B to C was the middle of the '86 production year, or about December'86/January '87, and only affected the S12 200sx Before January '87 they were Bs and after they are Cs, The 720 stopped production just before this so are all Bs and the D21 Hardbody began at this time so are all Cs.
