Hey guys i got a couple of questions i recently got a new body for my 79 suburban the new body is an 89 is there anyway i can keep my 79 vin so i can keep my collector tags if so somebody please let me know the second is ive heard alot about dually suburbans and thought it may be a good idea to try one out i found a one ton dually axle that will fit but would it be worth replacing the 3/4 ton 14 bolt i have under it now or would it not even be worth the effort and the last is somebody told me that you guys might know where to find pitman arms and other lift parts for a lift over six inches if you guys could help me out please let me know thanks for reading and hope to hear from you guys so i can find out which direction i should go
