No take a cold chisel and hit the perch in the weld corners, just a cut. Then use a big 5 lb hammer and hit down between the housing and perch. Pop right off grind a little and use again. Done it many times. The hole is the right size too!
better yet , get a new set of perches , cur one exactly in half on a band saw, keeping it very square and straight , then weld the half perches to the originals , using them to get the same angle on the halves, weld a small amount at ta time ,so as not to distort the axle , no fiddling with setting the angles , all thats left is to redrill the u bolt holes over 3/4'' -no biggee, I`ve done it .
and mine did move the frt of the spring 3/4'' , regardless of what know-it-all says !
