I'm about to buy a used crawford plenum from a local friend and was wondring is there any special bolts or gasket I need to get to fit it or I can use the OEM bolts?
You can use all but 3 of the stock bolts on the outside. on top you will need 3 longer bolts 2 for in the middle and one in the back. now for the inside you will need 3 very short 8mm bolts to fit in the six holes where your orginal bolts went on your plenum. when you take it apart you will see.
