As the installation of my rear D44 gets ever closer to becoming a reality a question on placement. Running 6-1/2" of lift front and rear give the "view" of a shorted wheelbase with tires moved to the edge of the fender openings.

The front was no issue as I have adjustable upper and lower control arms. Checked with the manufacturers before doing anything, but extending each 1" was well within tolerance and centered the tires just right. Also gave the alignment guy just a little more to work with when adjusting caster angles. Now to the question ...

I've seen spring perches and axle plates with multiple holes drilled so the axle could be move fore and aft 1", or so" from the standard placement. Can I accomplish the same by drilling or are these aftermarket plates and perches dimensionally different from the standard?

BTW, I am only looking to move the axle 1" to the rear.

Thanks!!
