Thanks Frank, I'll let you know, for now I'm going to cut off the threaded end of my dump U-Bolts for extensions.
It seams like a strange design for me to have the LH and RH threads. It is one of those adjustments that you make once and never change again while mounted.
Well I chopped the threads off of one of the Dump find U-Bolts and added them to the links with couplers. The height is set correct now and wheeled New Hartford last weekend with out any issues.
