Any of the ones that look like commas. Grab the rubber connector, the bolts that hold the TBI to the manifold, and the bent stud and nut. You need a 20 inch piece of 3 inch standard drain pipe, a 45 degree street elbow, and a filter that fits a 3 1/2 tube. If you can get an aluminum tube, you can use a filter for a smaller diameter tube. Make a two sided "box" from thin gauge sheet metal (aluminum or steel) to separate the filter from the heated part of the engine compartment, so it can draw air from behind the headlight and around the horns. Use a piece of rubber seal (part of a door seal will work) to seal against the hood.
