Okay, I have a feeling this post could trigger some folks. I fully appreciate and respect the fact that some people really hate it when a Trans Am gets frankenstein'd but that's what I did and just in case others have questions thought I would post some pics. Unfortunately, I am REALLY light on pics for this one. Sorry about that.
Back story is that I always wanted a 77-78 Trans Am. Not like, I wanted it for a few years, but like always wanted one! I put a picture of me, as a kid, with my bigwheel painted black and gold below that was taken in the late 70s or early 80s. So, yeah, since I was a kid.
I have a daughter now and she has been turning wrenches on this Trans Am with me every step of the way. For that I am blessed. I was looking around for a 77 or 78 for quite a while but they were either too pricey for me or in terrible shape. I needed something that was drivable, even if it looked like a mess. If I brought home a car that was not going to run for a long time, I surely would have lost my daughters interest (and maybe my own). Having a project car that you can upgrade and then drive again really keeps the motivation and happiness strong. Thus, I found a really decent 1979 up in Oregon and decided that was going to be the one. Then I went about fitting a 77-78 front end to it and there you have it.
This swap is pretty easy. For the most part the front ends are a direct replacement. If you are lucky enough, you can find a complete front end off a 77-78 and then you have all the parts you need. That was my route and the front end cost $500 from Second Gen Graveyard. I tried to list the parts you will need if you are starting from scratch. A google search can cross-check my work below but its a start.
Front bumper cover
Front bumper foam absorber
Front bumper reinforcement
Front bumper headlight mount
Right and left bumper mounting brackets
Center nose support bracket
Front spoiler center 1977-1978 (fiberglass)
Front spoiler side flares set 1977-1978 fiberglass with bracket pair
Trans Am Front Spoiler Kit (center and side flares)
Front spoiler backers (pair)
1978 Trans Am front grill - left hand (black)
1978 Trans Am front grill - right hand (black)
Headlight support
Front light wiring harness
Hardware to adapt front nose and tail lights (i didnt need this)
Front emblem panel crest gold
There are maybe a dozen or so bolts that hold the front clip to the quarter panels and chassis and all of them are fairly reachable. Just pay close attention to how many you removed and ideally draw some diagrams. I could go into detail here, but its really not needed. It really helps to have a friend when pulling the front end off and holding the new one in place. Dont tighten down all the nuts and bolts until the end so that you can line up the 78 front end as best as possible. Also, that nose support is fiberglass so unless you want to be really itchy wear long sleeves.
In my case, I still have the 79 spoilers but you could easily swap the 78s to make it look more like a clone. You can do the back bumper as well, but I have not attempted that...yet.
