To Restore or Not to Restore

I know these cars are getting harder to find and someone out there may want it more for the restoration purpose than what I want to do with it. That picture was taken in 1986 right after a new paint job and the bumper had not been reinstalled yet, the custom ordered centerlines with 4 in pattern were new as well. The car does not look this good now! My plan would be to change the front and rear suspensions and move to the 4.5 bolt pattern. Install the roll cage I purchased in 1988 and lighten the whole thing. The back seat must weigh at least 100 pounds alone. The car is legit short of the engine block, third member and Torque convertor.
