I agree that front shackle angle is crap. I would also suggest wheeling it and trying to flex the front as much as possible to see if you can get them to settle.. If that doesn't work, I'm not exactly sure what the overall length on the marlin springs are but you could get some of the long toyota rears I believe off the 89 toyota 2wd and swap out just the top two leafs into the marlin springs, I don't know if anyone can verify this but I do believe there are a little longer and do move your axle a little further forward than the marlin's do so they should give you a better angle without having to cut off your hanger. And last, you could possibly try running a banana shackle in the the opposite direction?? Not really sure hoe that would work out though.. Just some food for thought!
