Pinion angle

If that is the case do you guys suggest I cut the perches off or do you think a 4* shim would work. Its possible the shim may be to large and not allow for the locating pin to seat on perches. This is just for planning purposes as I still need to order my new 6 Leaf +1 EPSO's and see how the -5* looks before I make any changes but chances are I will need the shims or re-weld some new perches.
A 4 degree shim is totally acceptable.....I always buy the type of shim that has a hole for the spring center bolt that way I know for sure tat it won't move or slide out but sometimes it means that you have to buy a longer spring bolt??? The pin for the perch should still be there for alignment.
