Only 1978 or older Suburbans were able to either have barn doors or tailgate,after that the body was made for one or the other,and as stated by TommyM, its a real nutcracker to try converting one with the gate to a barn door version,though it can be done..............................................................................................................................................................................................................I had wanted to put barn doors on my '85 and even found a pair at a local boneyard with the same paint scheme as the truck for 50 bucks too,I was pretty bummed out to learn they were no longer an easy bolt on swap like they used to be...GM did us no favors by making the bodies different....luckily the junkyard gave me a refund ,so I didn't have to sell the doors myself to recoup my 50 bucks!..Out here in rustville,a truck with a decent shell is worth a grand,and if it runs,drives and stops,its worth double that...I'd say 800 bucks would be a really good deal for that truck,if its not rotted--I'd just stick another SM465 in it and drive it,its enough of a job just replacing what they put there originally,though swapping an automatic in isn;t that difficult provided you have a donor truck for the parts it will require..steering colum,possibly driveshafts and crossmember,etc...its easier than putting a manual in place of an automatic,I've done both and neither was much "fun"...
