Just cleaned up my rear 44 cut the old perches off getting ready to weld on my Barnes perch kit. And so I have an issue. I’m lifting 5.5 in the front and soa rear but I’m hoping to remain at about 2-2.5 inches or rake so looking for 7.5-8 in the rear. So I think I will get about 6 in the back. Witch makes me think I need to through a 3 inch shackle in the back. Should I tack the perches on and bolt it in and then get the front dialed in see if it works then get a shackle that’s the right size?
