I'd just make a different set of brackets. I have a customers 40 in now that we will be frame and body stretching, adding 62 axles with coil conversion, so I can look at the brackets after I get the frame work completed.
You can adapt to your liking as long as you keep the radius arm spacing correct of course.. Probably able to go forward another inch or so before the upswing in the frame where you'd need to add a wedge to the front of the RA bracket.
No, customer wanted extra wheelbase.
Have another one to do in a few weeks. We'll be stretch the body and frame 18" (tub sectioned) and then adding coil conversion front and coilovers rear.
Available as a kit like my others, will be working on our next two and once those are done I will send...
Getting the 40 front conversion kit dialed in. We'll also be making a rear kit with 18 stage compression and rebound adjustable coil overs.
More to come in the next week or so.
