Are you talking about the circled screw?
If so, use a screw similar to your other plastic screws.
I wouldn’t use a self tapping with the drill bit end. But I think they have a similar appearance to a sheet metal screw
Depending on how perfect you are trying to make it, just use something close, doesn’t take a lot to hold indicator.
Column screws are difficult to get. Junk yard or eBay.
Hello,
Anyone have experience with headers or manifolds for 86 K10 350 with Vortec heads?
I’d prefer manifolds over headers. Not looking for high performance.
Have scoured internet but can’t find a straight answer.
