We have a '69 300 Deluxe SS396 Chevelle. Could the same be had on an el Camino with rubber mats and base seat trim?

According to Dan Carr, the expert in this area, a 69 El Camino Custom, 13680, could be had with the SS package, but not the base model 13480. You can see this at: www.chevelles.com/shop/ss_ident.html :D

I had a 69 SS396 chevelle for about a decade. I wish I hadn't sold it a few years ago.

Roger, Tommy! There are a few cars I wish I hadn't sold too: 59 Pontiac Catalina 389 Tri- Power, 62 Impala SS 409, 4.56 Positraction, dual quads, 65 Mustang 2+2 Fastback 289 HiPo 4 speed, 69 Pontiac GTO, triple black, kinda wish I still had my 78 Corvette Silver Anniversary, but it rode kinda rough with the Gymkana suspension, not really a muscle car too, although I got it over 135 MPH and still pulling, Oh yeah!, my 1940 Ford Deluxe Coupe, 53 Merc flathead powered, sold it in 1960 for $160. It was just a 20 year old car then! And a few more! Little did we know what those cars could be worth in the future! :(
