for the front springs, I used the factory rear mount, and put the marlin front hanger in the 1" forward orientation... and basically the tube steel is flush with radiator support.. you can kinda see it on the first page...
for the rear springs, I followed the instructions of moving the forward mount 6" towards the front of the truck from the stock mount, and as for the rear I ended up having to move the rear mount 3" back... but I think this is a case by case situation.. I had to then set my axle on one of the spring offset mounting points in order to get my wheels centered in wheel well...
I recommend just taking it all well into position to see where it all sits before finish welding..
