5.0 throttle body bolt/stud size

[CantedValve]

I am trying to figure out what the bolt/stud size is for a Fox body 5.0 throttle body. Anyone that can help?

Also, does anyone know what the outside measurements are of an EGR delete plate?\

Thanks!

IIRC the bolt size is 3/8. The egr delete plate is the same outside dimensions as the throttle body and upper. When I pulled off my EGR I just used bolts instead of studs.
What are you trying to do?

I am trying to build an upper plenum for my intake. I am using an EGR plate as a mounting flange for the throttle body.

3/8 sounds right when I look at the gasket (I ran to Autozone to get one to measure for EGR plate size... boy I'll have to tell you about THAT sometime). I halfway expected that it would be metric.

Thanks for the info!

I thought it was metric, but it has been awhile.

Me too...I wonder if I still have a set of studs in my bucket of bolts...might have to take a look this evening and see.

I just traced a piece of alum the same size as the throttle body.. Then went through it with a 70mm hole saw. Think I used 3/8" thick alum..

IIRC, I just grabbed a long threaded stud from the hardware store and cut it into 4.. 5/16, or 3/8,m I believe.

I was thinking it is 5/16". I used chrome bolts to hold my TB on and I know for sure it was not metric.
