I purchased the 1954 Alpine knowing there was a reason for the body putty under the rockers. After getting the car home, we discovered the rust to be much worse than I assumed. The car had a V-8 with a stock front end and to say it was cobbled together is a kind description of the work. There were traffic signs posing as floor boards and the putty was inches thick in places in the body.

My son Jim and I completely disassembled the car and discovered it needed all new floors (including trunk, door bottoms and a new firewall.) The original "fabrication" consisted of metal screws and sheet metal sign pieces screwed together (no welding), and then everything covered with body putty. We removed the body from the frame and sent it to the dip strippers to take the body to bare metal. While the body was at the strippers, I completely modified the frame.

I removed the stock front end assembly and installed a Ford Mustang II crossmember, tubular A-arms, coil over shocks, Mustang II spindles, 11" disc brakes, and a power rack & pinion from "Fatman". An "Iditit" tilt steering column controls the new front end. Ford V-8 mounts were added and the stock frame x-member was removed. A new transmission mount for the Ford AOD ("automatic overdrive" four speed) was fabricated. New early-Mustang leaf springs replaced the nine leaf stock units. A new rear shackle mount had to be made for the springs. They carry a narrowed 9" Traction-Lok (3.08:1) rear end, with drum brakes. Since the stock frame is underslung, a hoop shock mount was made for the rear. A fuel cell, electric pump and braided stainless fuel lines were added including a return line for a (future) fuel injection system later.

Upon return of the body, a setback firewall and new floors (including trunk) were made from 16 gage steel and welded in. A power-boosted brake system was hung on the fire wall and new steel lines w/ residual valves were installed. Other replaced parts include: aftermarket wiring (all wiring is done by my son, Jim), taillights, 66 Mustang seats, a Mustang floor shifter, and a Lokar emergency brake lever system. After replacement of the structural panels, the car was assembled with the new parts to finish construction before painting.

After fitment of the new parts was completed and rechecked, the car was completely disassembled for painting. Now the body shop is completing the body work and primering the car so that we can be reassemble it before it is painted the finish coats. The body shop, Sporty Car Garage, is painting it a Mazda color that matches the original Alpine Mist Blue of the car (think Grace Kelly "To Catch a Thief" blue). When I get it back from Sporty Car Garage, we will install a tan interior in the car.

The engine in the Alpine is a stock 1991 Mustang 302. The stock fuel injection will be used if we can figure out the wiring.
