Ill use Jon B.'s famous line..."The year matters"
I installed 5 points on my 94 and followed the "recipe" in the "how to" guide and it wasnt too hard...But I had to "drill out" the holes where the harness mounts behind the seat....
There were threaded lugs there but they were covered up, I also used the Autoform rear panel but I had to modify it with a dremmel tool for the slots to line up on my snake.
I would say it took me about 4 hours,going slow.
Cheers,
