Shouldn't be difficult to do that. Just cut and tap, or cut and weld in a bung. Find some misalignment spacers that are the correct diameter and width (or close enough to modify easily. You just need spacers, not high misalignment spacers, so they should be relatively easy to find/make.
Excellent thanks! I'll start diving more into this then. I think I'm enjoying my rig (and IFS more) when I'm not fighting problems.
