i have an 88 vert and i'm thinking of swaping over to the 4eye style. i'd also like to do the interior as well. the car is carbed so that makes it easier. i know to switch over the dash i will need to swap the dash mount behind it as well. my 2 concerns are my steering colum and head light sw. i think i will just use the early style dash harness but i'd like to retian my 88 colum. can i use the 88 and just swap over the 88's colum trim?
