After getting a late start in the garage (double-checking suspension CAD one more time) wood was cut to length to mimic the A-arm lengths, the ends drilled and rod-ends screwed in. The lengths were checked then bolted to suspension pivots tacked-in for this test. It’s a relief to see that nothing terrible is wrong; no visible toe change and the suspension’s free to move beyond its full range without the axles bottoming out or trying to disassembling themselves – good. It’ll all be double-checked because the upright’s weren’t precisely positioned but it’s looking good.
