Guys I'm trying to compile a full list of all the different length VW irs axles. If you guys know of any other lengths please let me know what they are and what they came in. I figure this would be a handy list to be able to reference. Here's what I have so far.

15 1/8 924 auto
16 1/8 924/944 manual/181 thing
16 3/8 bug manual
17 1/4 924 auto
18 3/4 bus 74-79 manual
20 1/4 914 manual both
20 1/2 84 Van auto diesel drivers
21 84 Van auto gas drivers
22 1/2 84 Van auto diesel passanger
22 7/8 84 Van auto gas passanger


17 7/8 ?
21 1/4 ?
16 7/8 ?

Thanks,
John

Nice work. Now the trick is to match the axle length to a arm length/width.
2x3 = 18 3/4"
3x3 = ?
2x4 = ?
3x4 = ?
