Lucky, sure.......lucky that I read the FordBarn posts!
I don't know. I've destroyed many a tight bolt in my younger days by pounding/torquing too much too soon. I've learned the extreme patience required to apply mild heat and WD40, get something to move just a smidgen in one direction, then a smidge the other direction, reapply WD40, then do this forever, if needed. Eventually nearly anything comes loose with this method. The thing is, I thought the perches were keyed and I was going to heat, pound and air hammer them. The twisting advice, and the pictures of the homemade perch removing tool (made from a front spring u-bolt set) got me thinking, and led to this result.
Either way, I'd rather be lucky than good any day!
