well i guess the question i have now is to go under the frame or through. going under will be a bit easier and i can always cut off the shackle hanger and go through if i decide to.

what degree of angle should the front axle be tilted up towards the t case for proper steering geometry?

also how am i supposed to know how far i am moving the axle forward from the stock position? what can i use as a reference point?

thanks again everyone.
