I have the bolt type stanchions not the Dzus type. I assume that there are captive nuts on the inside of the body where the stanchions attach? Looks like a real pain to free up these bolts. I've allready started soaking them with PB Blaster. Is it worthwhile to drill access holes in the metal cover that hides the nuts. Any advice on removal most appreciated.:grumpy: Also ...anyone have a spare set of "tenon plates" mine have gone missing.
