I finaly figured out how to bolt in the new seats. Unbolted both frames on both sets. Then were the factory frames were riveted i bolted a 1/8 flat steel to the new buckets. I then bolted the old frame i took off to the factory mounting . set the new seat on top off old bracket were the flat steel is marked it added more flat steel were i marked . Then drilled 3/8 hole into seat frame and flat steel. Bolted together every thing lined up with factory mounting points. It took about 2 hours first seat and about 45 min other seat. Sorry i don't have any picture
