What methods are you using
to drill the holes correctly in the frame to mount slam RE7's in the original coil spot. What a freakin headache. I have one half way done, but it took me two freakin hours.

Re: What methods are you using
im assuming you mean in the rear because the front plates should have already been done. in the rear I went and bought a hole saw just big enough so i could get the fitting through, then just ised a good quality bit for the3 other 2 mounting holes. I think i had all 6 holes drilled in less than half hour

Re: What methods are you using
I had the same problem drilling my holes for the bag port. The hole is a 1" size. I went through 2 Unibits. But I was drilling through the CPP bolt-in cnotch, the frame, and the stock backing plate. It was a total PITA.

Re: What methods are you using

Re: What methods are you using
Carbide 'burring' bit & high quality drill bits. I used drill bits stepping up to 13/16" & then opened up the hole as needed w/the carbide burring bit. Took about 15mins ea. side.
Many suggest the hole saw method but I used one on a hole I was drilling on the top side of the shock crossmember. Standing above the work, soaking the hole w/cutting fluid, & being able to use most of my body for support, it still took 5~10mins of solid drilling (about 25mins stopping to limit heat soak on the bit) & this was only 1/8" thick single wall mild-steel. I can't imagine lying on your back, pushing up w/only your upper body for force, & trying to drill through almost 1" thick steel (frame + frame support + c-notch support + shock crossmember support). The carbide burring bit made quick work of it. I bought an 8pc kit for about $150 but now I have them for other jobs (I could have just bought one bit for the job).

Re: What methods are you using
Not all holesaws are created equally. Trust me on this one. But, there's more than one way to get er done.

Re: What methods are you using
This was my assumption as well. At the time though, Home Depot was my only source for the hole saw so that's what I had to go with. After going through the BS I went through w/the holes I did on the top side..... I knew I had to seek an alternative method.

Re: What methods are you using
You could also you a torch to punch a hole, then clean it up w/a uni bit and grinder
