Thanks for the offer. Here's the thing though. I had always thought TBI units were all pretty much the same. But when I look them up on Rockauto, they all have different part #s. And Wickipedia says that linkage and spray were improved in 1991. I am always amazed at how many things change from year to year on any model. The beauty of these rigs is that there is so much that can be swapped around between the different years and models. But I have had headaches before when I try to second guess part #s. It may come to this. But, for now, I am still hopeful to find a 91 TBI unit.
