You might want to check the id of the outlet. The 2 1/2 inch will serve well while the 2 or 2 1/4 inch are going to choke you down a bit. the bolts and studs are standard exhaust items. If the inside of the manifold is tapered, you can get a half donut that goes between the spacer and the manifold or you can go without it using a full donut. Might suggest using long brass nuts on the studs. Makes future work a lot easier.
