Installing subframe connectors

OK, so got all the holes drilled, bolts fit good. 1/2" bolt fits snugly inside the crush sleeve made from 3/8 pipe. This pipe has a 1/2 ID, and 11/16 OD! Why do they call it 3/8?? Haha. I cut the pipe to fit tight inside the frame, worked it up inside there thru the holes on the bottom. If you get 1 end close to a bolt hole in the frame, you can stick a large Phillips in there and lever it into position. Pretty tight fit, they stay in there! Using 1/2" grade 8 bolts at the rear, instead of the 7/16 ones supplied with the connectors. The 7/16 bolts will work at the front. Here's a few pics showing the bolt in the crush sleeve, and the sleeve inside the frame.
