Im planning my 4r70w install which will be 1.5" longer than my C4/Dana 20 in a cut Bronco. The rear axle is too far forward anyways, so my thought is to install these Duff Axle Alignment plates to move the axle back 1.25" to avoid shortening the driveshaft and getting the wheels closer to center of the well.

I have read you can just drill new holes 1" forward in the leaf spring perches but these seem like a stronger alternative. I have WH heavy duty U-bolt and U-bold plates, so I figure I could drill the U-bolt plates to align with the Duff alignment plates and Im good to go? I have checked for axle travel clearance; brake lines have enough slack and shouldn't have any wheel rub.
The alignment plates are 1/2" think and I dont need more lift, so I plan to remove the bottom two WH leafs to make up the difference. Will removing the two bottom leafs change the rid? * The alignment plates ar about the same length at the bottom leaf ~8".
How do we like my plan?
Thanks,
