CV Clearancing Swing Pan for IRS Conversion

Chris Paterson

Hey guys. I'm not an offroader but I knew you guys would know the answer. I've upgraded my swing axle pan to IRS by welding in the pivots with a jig. I don't have an IRS transaxle yet. I'm at the point in my project where I'm going to go and get the pan sandblasted and powdercoated. I've read that you have to clearance the swing axle frame horns to accept the CV joints off the irs transaxle. Without a transmission to bolt up can someone tell me where (measurements to the center point) and how deep I need to clear for some 100mm Bus CV's?

I do have my old swing axle transmission, can I use that to know where the axles will come out? I also bought some 4.25 ID steel tubing to cut a piece out and weld into the framehorn. Any help would be much appreciated! Also I think this will be a good post once some answers come along, since there isn't any info on the samba that I can find.

Here's a pic of a stock '74 IRS tranny and CVs on a '68 swing pan. As best as I recall, I clearanced mine in the same spot as where the swing axles rode. I described my swap in some detail here: http://www.thesamba.com/vw/forum/viewtopic.php?p=4446894&highlight=#4446894

Here's the clearance I built into mine:
