I am new on this site. I have a 91 comanche. I am puting a 6.5 in lift on with SOA in the rear. My question is do i need to use a slip yoke eliminator kit or can i just get the right angle when doing the SOA and get a longer driveshaft? also what other modifications need to be made with this big of a lift? do i need to use a drop pitman arm. I have upper and lower control arms, adjustable track bar, brake lines, and 6.5 coils.
