Does anyone know the diameter of the hole for the clutch master cylinder in a 1996 k1500?

Are you trying to cut the hole for it?

Yes I want to pick up the correct hole saw

4:50 for visual and 1" 3/8 for the center hole 23/64 for the bolts

I will have to research to see if they make that master cylinder in the newer style

If you look at what I wrote on the picture (that's my pic) you'll see there's not one hole. There are two. You won't cut that effectively with a hole saw, or anything else. The two different sized holes were stamped out of those sheetmetal panels before they were bonded.

I took the old (smaller) master cylinder hole on a '94 and just kept enlarging it until I was able to get the master cylinder to clock into the bracket, then shimmed it tight with some plastic-y gasket I'd found in my bolt bin.

What technique did you use to enlarge the second hole? Did you have the clutch pedal installed while you made it bigger?

And sorry that I stole your picture. It was the best one that I could find!
