If you have both of the blocks there, can you measure them and let me know how tall each of them are. I believe the NBS blocks are 2" and the NNBS blocks are 1-1.25" but I want to confirm that. Thanks.
Does anybody know off the top of their head what the height of the NBS and NNBS blocks are?
This thread saved me $75. I was going to order the Total Performance lift this morning but the u-bolts wouldn't fit in a Flat Rate box(shipping was going to be $60) so I only bought the front spacers. Found this thread and went to the local junkyard and got NBS blocks and u-bolts for $25. NNBS like mentioned above are 1.25" and NBS are 2". Perfect solution to needing a little more height without having to stack blocks or disassemble the springpack to install a zero rate or AAL.
You do need longer u-bolts but the NBS ones fit perfect. They're 3/4" taller just like the blocks so everything will look 100% factory when done.
