In theory you should be just fine. The concern on the front is not as much the pinion angle it is the caster angle. If you weld the perches on top of the axle at the same angle as the originals, you should be close enough.Stonefly said:I'm not able to place the axle under the Jeep today, for a test fit. Just need to know if welding the new perches parrellel to the stock perches will give the correct pinion angle. Stock YJ 5-leaf spring packs will be used front & rear. If so, I can weld them on & cut off the stock perches & shock mounts tonight. Anyone else?
