We had an accident a few months back and still trying to get our spark back to 100(ish)%. We patched hull, pumped water, 6+ oil flushes, spark plugs etc. now putting it back together I can’t get to the two bolts in rear behind seat (attaches top to bottom) to go in. Also having issues with drive line. It’s all connected but does hard rights and soft lefts. What am I missing? Please help!!!
