A stop pin as far as I Recall..

Give me a moment.

No Stop pin, it must be internal.

The needle probably needs re-aligining with zero

Thanks TT

Any ideas how?

Pull it off, turn it to 0 and push it back on.

Simples:o:o

Next question--I am buying up a few clocks/guages for my post IVA dash.Would any electric impulse type rev counter/tacho work accurately with my sierra cvh. Also is my oil pressure switch fairly easily adapted to a tube for oil pressure guage.

Thanks in advance.

Any wisdom on previous post please?

most reve counters will take a coil input with a swithch on them for the cylinder config

I would use a non capilary electrical oil guage

Does the oil guage need a different sensor to replace the switch

Of course; they usually provide a pressure switch output, too.

Normaly a Tee piece is put into the block, the pressure switch and a pressure sender then fit into that.

The disadvantage usualy of electrical guages is that they only do a 180 sweep and not 280ish like the capillary ones.
