You know, now that I think about it, I may just loosen up the winch on the plate so I can slide around until I get those bolts reattached and then tighten the winch back down. Hmmm. Thanks for your reply.Yes, the top two bolts were challenging to tighten. It took quite a while to figure out the right combination of 18mm deep socket and extensions to get it done. I watched many install videos prior to the installation and it seems pretty much everyone found tightening these bolts to be a challenge.
