i got these off an 85 3/4 ton burban then had them rebuilt. the codes on them read 36 and 333882 and are supposed to be from a 74-80 engine. My uncle had them rebuilt for my truck but then they wouldnt work with my tbi system so i threw them in a couple pillow cases and have been sitting in the garage on a shelf for a better part of a year. i had plans to build another engine but i have alot of bills to pay so i need the cash more. i would like to get 250$ for both of them.
