a buddy of mine had some front 4 inch lift springs for a full size short bed chevy that he was going to give me,but they would not fit. i cant remember exactly why,tht was last year,but the length form eye to eye on the chevy truck was different.it was shorter,if i remember correctly.it seems that i measured his rear,too, at that same time,and decided that the rear spring wouldnt work either.
as was stated,if you can cut/grind and weld,its perfectly fesible to move the hangers to the appropriate places to accomodate chevy springs.id do a shackel reversal while youre at it. in the front you could move the rear hanger,in the back youd probably have to move the rear mount,due to the location of the front eye on the frame.
i dunno-that sounds like alot of work to save $40.
