Don't know the brand of the air filters, they came when I bought the car. The four months, five days a week to complete the restoration was also with my body-man brother in his shop with a lift in Deer Trail, Colorado. The transmission and overdrive were resealed. The engine was already in good shape. I replaced the front springs and some of the steering parts. The lower part of the front shroud was replaced. Some previous poor body work was corrected. The right front fender, I believe from a donor had surface rust inside and the left rear fender had to have a small section cut out and replaced We repainted the car with PPG base-coat, clear coat.
The car originally was Colorado Red and changed to Metallic Golden Beige before I bought it. Had to finish the color change underneath, lots of sanding, grinding and priming etc. Shocks, power brake booster, oil pan, radiator etc were removed, stripped of paint, primed and refinished. Replaced all of the brake lines and installed a new electronic SU fuel pump. The interior was in good shape, made a few repairs. I refinished the dash wood with the pour-on two-part epoxy finish (Evirotex Lite) purchased from Hobby Lobby.
I racked up about 9000 miles on my 87 El Camino traveling to and from the 68-miles to Deer Trail Colorado from my home in Lakewood, Colorado to work on the Healey.
