[Big hammer]

When I reinstalled my Tudors body on its frame, I put the bolts into the body and slid the body block up on the bolts. The block holes where tight for the bolts, if your blocks want to fall off wrap duck tape around the bolts holding the blocks up. When you lower the body get close and align the bolts into the frame, remove the tape lower the body completely tighten the nuts. I did this by myself, when you removed the body just us the same process to reinstall in reverse.
