Just a few more things about the El Camino. I noticed the front seats were different; drivers looked like a Regal Ltd. seat while the pass. seat looked stock. There is a 7mm screw in the wiper switch area which looked odd. Along with the others, I thought the "Ltd" emblem on the dash is from a Regal or possibly a full-size '77 Electra Limited rear quarter emblem. I know the drivers seat could be had with 6-way power but the only recliner was on the pass. side if that was even available on an El Camino or Malibu for that matter. Even on my '84 Cutlass Brougham, I only had pass. side manual recline, although I did add a driver side power recliner to go with my 6-way power seat. Parts from a Buick Riviera fit right in!
See that you passed on this car anyway; good choice. That looked like a cobbled up mess.
