Back spacing....

[Harleighguy]

WHAT is the backspacing on a M34 riveted center rim as compared to a M35 welded center rim? I can SEE in pics that the M34 rim has less backspacing, but WHAT are the dimensions?? Thanks in advance!

about an inch difference, the M34 wheels can't be used for duals as the tires will hit
