This is on the rear end - I'll be using them for caster adj on the front end like GM recommends - all the way back or all the way forward. I guess like I've got them now, it would be zero caster??

Squee - I'll try that when I start with the front, but my impression was the gaps at the front and back are bigger than the caster shim - it'd allow back and forth arm movement on the hp. I'll check into that. I've never bent a hp, but it dawns on me it might be better to support the ends rather than the middle. I don't have enough to to both unless I get more. I bet you're more likely to bend a hp at the end that in the middle....

I got the rear finished last night and really like how the 3.3 stuff fits and looks. TRX really made those pieces hefty this time. The tbs are thicker than the UE tbs. Will get to the front end after lunch and a few chores later this afternoon.

GM360 - in the middle it makes for a tight fit, arm can't move.
