It is not a hard swap, i'm just finishing up swapping a 95 front clip on to an 88 (That includes the cowl). An if all your going to do is swap out the front clip. you will have to do some modifing with the light harness, besides that it bolts up nicely... Unless your good with a welder you will need to use an 88 - 91 front bumper as well.
I took it to the next level and swaped the entire guts of the 95 into the 88. Including swapping out the dash, firewall, so all my electrical connections from my harnesses would seal nicely.
I don't have many pictures as i kind of lost interest in taking pictures of progress. But i got some good dismantling pictures here www.supermotors.net/users/xxxyank of both the 88 and 95
