Bolt Size ??

[SS/GN]

Looking for the bolt size for
Dog house bolts
Heater hose tube retaining bolt
Steel Vac line retaining bolt (under throttle body)
Thermostat retaining bolt

Thanks in advance for any help.

they are M8x 1.25 thread
the doghouse are longer and length varies depending on what plenum you are using or if running a rjc AD plate . stock is about 24mm (1 inch) with power plate go 30 mm
the heater clamp and vac hardline bolt under throttle body are shorter about 15mm (fuel rail are same size )
thermostat i think 20 mm works

I can't recall all the lengths off the top of my head but here's a picture of my intake bolt kit. It should give you a sense of scale.

I forgot to show the water pipe clamp in that picture but it's the same as the Vac line bolt and the 2 fuel rail bolts.

Thanks so much, it saved me taking them out of the engine. I want to start getting some stuff ordered for my next project. Really appreciate the input.
