Centering pins for rear end?? non existent?

[HarleyPhreak]

Hey guys, i bought 2' blocks from the local X shop, chopped my unbolts off and jacked up my rear end to put the new blocks in, only to find out my truck has neither male or female centering pins.. ??? needless to say installing the blocks would be impossible and the new unbolts that came with the kit where too long and i had to order new unbolts while my truck sat out of commission for 3 days... another thing interesting was just making the truck the way it was in the first place... with no centering guides all i had to go on, was the shadowed smudge of where it used to be....
i have a 2006 ford f350 harley davidson edition 6.0, it has a 6' BDS lift.... only conclusion i can come up with is some sort of aftermarket axle... it did have a fresh baracode sticker on it, that looks out of ordinary cause its newer shape....
Any suggestions? is this normal for any ford trucks? what else could i do to get the 2" i want... my truck is a monster on 40' tires, but i hate how it sags when i tow... if i haven't been clear enough place feel free to ask.... I'm totally scratching my head about this..

I work in a fab shop, and i can pretty much do anything with steel.. im just thinking out loud, but i could easily cut off the male side of the block pin, but whos to say it wouldnt eventually wiggle its way out with no pins to secure it inplace? infact, even a better question, how did the previous owner or who ever installed the lift know they where bloted down in the right spot with no real guide? atleast i had there smudge marks to copy??? so confused ???

That's weird man I've never seen that

mine has pins

are you saying the axle has no hole on the pad or the spring has no pin ?

I don't see how this can be...What's holding the spring pack together??
