Basically the 95+ tail lights have a rounded portion along the front edge, while the 91-94 is straight down. Essentially I cut the lense from the top corner where it starts down and forward, straight down. Give me a week or so and I'll get some pictures taken when I do the second lense.
The 2nd gen. front fenders and hood must have the top edge of the 95-01 front radiator support, all the way to the back corner of the hood. I started to cut that top third or half of the clip off, and retain my 93 front end on the 99. I settled for keeping the whole 99 front clip intact, and I have bought 95-01 fenders, hood, bumper, etc. The bumpers are shaped differently also, it would look better to keep the bumper matching the front end model, and the bumpers mount differently.
To swap the front end parts, the work to graft the top edge of the other clip is the best way to do the conversion. There are evidently some aftermarket fiberglass parts that may bolt on. Good luck,
