SAS and SOA coil question

[Rwrighttt]

hi all, searched and i can't quite find what I'm looking for. going to be sas my explorer. i have a super lift 5.5 on currently. plan is to keep the stock buckets just bang some of the retainers out. to match the SOA i have in the rear, do i go with 3.5 bronco coils? or 5.5?

all the searching I'm finding is i have to get the 5.5 coils, and might have to add a block in the rear to level it out. but then i find out 3.5 coils is what i need.... confused!

If you measure from the bottom of your frame to the where the coil seats in the buckets, I will try to do the math for you based off the f150 coil buckets I used on mine with 5.5 springs
