carb numbers

[smokn03]

where can i go to find carb numbers to see if a carb will fit my truck?found one that looks the same with the electrical plugs in it.but says it is for a 1983 car.and my truck is a 85.here are some part numbers if anybody can tell me anything.17083452 and 22-3536.those are the two numbers i have for it.will this fit my truck or is it different for 83.oh and the only visual dif is it has a cylinder you plug in on the front of it hooked to the linkage not the choke it is still on the back.maybe i can just take that part off.
