would these injectors work in my truck? i found some used ones for a good price but im not sure if they are the right ones

 

I'm no expert on injectors but I think those are the right ones. They need to be AA injecors. Need to match the numbers up somewhere to make sure. I'm not sure where to do that. How many miles on them? Did they come from a 94-97 truck? I don't want you to spend $$$ and be in the same boat you're already in. If they check out I would still send them in to get checked. I know you're on a tight budget I'm just trying to prevent some possible problems for you. If you get them and don't want to send them in and just stick them in, at least put some new alliant orings on them.
