No advantage to the MkIII box. The shifter is further back and that's about it. Some of them probably have the ABS sensor as well.

I use MKIII w-58s in several of my cars - just as SilverMK2 said, they really are the same, all the differences are minor; shifter sits back about 2" and it will have an ABS sensor on the top if the car came w/ it. I cant remember if I needed to change the reverse light plug but thats not a big deal either way. There is a slight difference in the gearing as well, the MKIII having closer/ quicker gearing. MKIII also uses a cast clutch fork w/ a slightly different throw out bearing - but either can be used. Lastly, I cant remember which is which off the top of my head - some W-58s have the steel center section and some are full aluminum (not the entire case - just the 1" or so thick section in the center).

I'm not sure this is correct. I'm fairly certain the gearing inside the transmissions are the same. Wish I had some of my old car mags handy to verify.......

well I dont have any printed info that confirms this but way back when I first got the '89 MKIII W-58 - I compared it gear for gear to the original one in my '82 MKII and they were indeed different.
