What size are the stock 1990 7.4L exhaust manifold bolts? I really need a set.
Does ARP sell something that will work? TIA Love the site.

OEM # 03909821 which are 3/8-16 x1 3/16" in thread pitch and length. I am sure ARP has something but most of their stock is on backorder due to shortages of some sort. We are having supplier issues.
