Stainless Bumper Conversion
In the last two weeks I finally tackled the stainless bumper conversion on my 80/81 Spider. It was relatively painless overall, with the biggest PITA being the restoration of the '71 front bumpers.
Here is what I started with:
a) Late '80 Spider with big, black rubber bumpers;
b) Set of vintage '71 front bumpers and a NOS grille, paid $700 for the lot;
c) Vintage '71 rear bumper, paid $700;
d) Conversion bumper brackets, purchased from Alfa Source, about $300 with shipping.
As you can see none of these parts were cheap. However, the supply of original factory made bumpers is dwindling, and they are priced accordingly. The rear bumper required a light cleaning and was a direct bolt-on. The front bumpers required more work than I had anticipated, as the stainless tops were badly stained/scratched and the signal lamps were in bad shape.
The old bumpers came off pretty easily, after I soaked the bolts in PB Blaster for a few days. Each bumper has two collapsible shocks that are bolted to the body with four M6x 1.00 x 100 bolts. Below are some pics of the bumper mounts. I found that I had to trim a bit off the outer edges of the front bumper mounts to provide adequate clearance for the new conversion brackets. See the pics, below.
I also removed the fake grille halves. On the lower valance the bottom grille half was attached to a "U" shaped piece that was tacked welded to the valence in three spots. I drilled these out and removed it.
