I just realized that my post that should have been on page 2 must have been erased by the newly organized "TDR Censorship Police". Ok, so I was making some lighthearted comments about Tim's weight and asking him if he was 5'4 or 5'5. Seems Tim may actually be one of the above mentioned editor's teenage son or nephew maybe? Let's all be nice to Timmy. On the subject of the rear calipers size, don't the hemi's, and some early Cummins autos, come/came with the 10. 5" AAM? Maybe this explains the diff in size. I have an 03 swb 2500 4X4 and was under the impression that the only diff from a srw 3500 was the overloads/clearance lights/sticker on the jamb. I had intended on buying the 3500 but the deal just wasn't there at the time. The same truck in a 3500 would have cost me about $1700 and I could get air bags for alot less. It's funny how some people just can't be happy with their choice without constant affirmation that it was the right one. Oops, sorry Timmy.
