Hi Captain. A quick question. I bought your kit last summer, and getting around to putting it in now. Does the kit include nuts and bolts for mounting the clutch master cylinder? I used a couple of 5/16 bolts that were in the kit, one had a unthreaded shoulder, the other was fully threaded and a bit shorter. There was only one 5/16 nut included. Lots of washers. Did I use fasteners intended for elsewhere?

A few other questions:

I am using a master cylinder off a 79 K10 I think. I am using a booster off a 1998 full size GM. They mount fine, will they work together properly?

I also have the proportioning valve off the 79 K10, is there a way to test it to see if it is in working order? Just pulled it off a truck in the junkyard.

I will add pics soon, but just wanted to comment on the very close tolerances between the bracket and the inner fender, between a full size GM booster and the clutch MC, and between the clutch MC and the firewall plug. I have the Wilwood 1" bore MC. Have you heard this before?

Thanks.
