I am currently converting to coils from leafs on my 69 and spent about 1/2 the day getting my no limit pan hard frame mount to fit like the instruction said. I think that there needs to be some better instructions on this thing. The first thing I did was line the vertical mount over the hole like the instructions said, mark and drill the holes, and I wish I wouldn’t have done that. I had seen several others installed and none lined up, but that is what the instructions said so I did it. Tolerances on the bolt holes are real tight and I didn’t want to Swiss cheese my frame so I had to massage some holes and blot it in 1 bolt at a time using a motorcycle strap to progressively ratchet and align the holes. Don’t align it on the oval in the frame, blot it like you had it use a ratchet strap to pull the mount back as far as you can mark the holes and drill them, you will save yourself allot of frustration.
This system is awesome and I am excited to use it, but it fought me for hours.
Look at this page for good pics on the mount that rob actually installed on his shop truck and you can see the hole dosent line up on his either.
