Does it take any special tools? I was thinking about using grade 8, 3/8 bolts with lock washers and a few spot of weld for assurance yet would still be easy to remove with a cut-off wheel. I got the 2 old ones off today and have some welding on the frame to do but almost ready to put the new ones on. The rear blocks seem to be fine, just new bushings. I made new bushings for them out of knylotron.
thanks, Ron
