you are going to need a few parts for that conversion,hood,fenders,filler panel below grill,grill and headlights,the rad support is also different,I just checked my panel cataloge and none of it is interchangable,I couldn't find the number for the 88 bumper style,but by looking at them I would guess they are different too.so I would say all sheet metal from the cowl up would have to be swapped out.a pretty involved swap.
