Wondering if anybody has a description or pictures of how it is best done. I have the mopar performance kit and will be using caltracs with their monoleaf springs.

What year and body style are you wanting to use the kit on?

72 roadrunner sorry that slipped my mind

I'm considering the same for a 74 Charger.

These were from a '71 Charger I did last year for a friend. Currently doing a '74 Road runner for someone else. Hope they help.

Front spring box:






You can just make out the rear shackle here:

How do you go about locating the holes for the front spring hanger? The back one i assume is second and you just line stuff up from the spring with the desired shackle angle.

there is a build on this at bigblockdart.com that i used, sorry dont know how to link it

if your looking to get the most tire clearances from the relocation, mount the front spring box outer side to the inside of the outer sub frame rail, don't center it I'm not familar with the rear spring hangars on that year B body, do they unbolt? If they do you may be able to cut a V in the rear sub frame and weld that hangar into the sub frame. See the picture attatched to see what I'm talking about. For locating the front spring bolt location see if you can buy or borrow a machinests transfer or center punch the same diameter as the bolt. remove the leaf spring and leave the stock hangar in place, slide the center punch(transfer punch) in an bang it into the rear sub frame, use that as your locating marks, do both left and right sides the trick is finding a 90 degree drill motor and short enough drill bits to use in that location after marking the location Greenlee makes chassis punches in a lot of different sizes that work excellent, there a little spendy for one or two times use but they cut a very precise hole, they do require a pilot hole to start with

Thanks for the replies. I will call the welding supply place tommorow, but where else would you go about getting a machinist transfer or a big center punch?
