I had 30 minutes spare today so the rear bar work came off. Underneath the car was easy U bolts around the transaxle, the triangulation bar work up to the body was a tad harder. Two 4mm plates with the body work sandwiched in between. The fact that a 4mm plate has covered the oil drain for umpteen years is a tad worrying. Might have to convince someone with a few 914 engines to donate one, hint hint. Tomorrow, I'll undo all 4 bolts and perform an engine drop.
