The 4.6 badges use adhesive only so I positioned them to cover the 2 existing holes. The GT badge uses adhesive only(no bolts). I used a credit card to slowly work under the badge then start lifting it up. It took some time as to not crack them(maybe about 2 minutes per side).
The 4.6 badges are only about 1/2" longer and taller than the GT badge. Looks are definitely deceiving there. When I got them in the mail I was like, "Wow these things are going to be huge on the fender!" I was tempted to paint them to match, but after I put them on I like the contrast.
I got them from Late Model Restoration Supply(www.50resto.com) for $9.95 each...MUCH less than repairing the holes and repainting the fenders(that will get done when I get my new hood and painted racing stripes years down the road).
Just got my GT A emblems yesterday. Now the deal is what to do about the vinyl stripes. The directions say the temperature needs to be no lower than 45 for a 48 hour period after the application process. I don't want to wait for Spring!!!!! What to do???? I would love to put them on myself, but I have no heated garage to do this in. Any suggestions?????
