When I ran mono springs in the 70's in C/SM we drilled a hole thru the spring. A cobalt bit is the way to go, or you can sharpen a regular one over and over. If I remember I used an alien head bolt with the head on top into the spring perch. Used a threaded piece of tubing as a bit on the bottom. This way it was pinned in the top an bottom

thanks for the replies , a cobalt drill bit is the answer. I knew I could count on Class Racer.

It wont take much to drill through. We used 1/4 or 5/16 allen head bolts for locating pins.

Drilling safes open I have bits that will work. You can buy them publically. They look like a masonry bit but made for hard plate found in safes.

Carbide or Cobalt drill bits----tungsten bit if you can find one ---theses bits are very brittle so use care when handling or using them---- VERY slow speed lots of oil or coolant,----- drill press only NO HAND DRILLING so as to not work harden the material or ruin the drill bit-- DO NOT RUSH TAKE YOUR TIME doing it--better yet put it in a mill and use a carbide cutter to make the hole --FED 387

Or you can buy a set of Calvert split mono leaf springs. They have the locating bolt that goes thru them.

There is a company called Flex Form, they make composite springs that will save weight, they weigh 8lbs a side and last for ever. Just a suggestion. About $400 for the pair.
