Hey All,
I'm brand new here. I owned a 92 Sierra as a youngster and have just picked up an 82 LWB Stockman in serious need of TLC. In terms of mechanical, I'm new to Suzuki and the F10A so I'll probably be here asking lots of questions as I go

I'm compiling a list of parts I need to get the thing running again. The car was sold to me as a "runner in parts" but that is far from the case. One of the pieces I'm missing is a plug (?) from the side of the intake manifold. It's labelled as number 10 in the attached diagram.
Can anyone tell me the thread and bolt size for it? I'm assuming I can just chuck a suitable bolt in there as opposed to the grub screw looking thing in the diagram?
Cheers
