    904 band adjustment question

    I read an interesting piece on this which said snug both bands (driveshaft wont turn either way) then back off each till the driveshaft will lightly turn (opposite rotation for each band) then loosen another 1/2 turn & lock down the nut. I did this on the band on the side but on the inside band...

    pinion angle Q

    Good info Kim, much appreciated. the 3/8 I needed that to get some longer ones. right now the jack stands are under the 8&3/4 & on the front subframe(s). the car does appear to be level or real close to it. With cement blocks I have my weight on the seat & 9/10 of a full fuel cell of gas weight...

    easy 904 band adjustment Q

    a guy posted that he loosened both nuts/shanks then tightened one till the driveshaft can just be turned with one hand then loosen it another 1/2 turn then locking it down then the same way with the other band except you turn the driveshaft the other way. I may have missed repeating something...

    easy 904 band adjustment Q

    I can get a 4.2 lever & was going to back off the allen bolt on the side that I had read about (they said leave several threads, just enough so it stays engaged).

    7&1/4 vs 8&3/4 OAL. both BBP

    have a 7&1/4 in a 73 dart & the mag wheels/tires are very close to the outer fender. I would like to swap to an 8&3/4. Are these pretty much the same total width? thank you for your time. RR

    Abody SBP 7&1/4 vs 8&3/4 SBP overall length

    the wheelwell radius has been trimmed to where all of the wheel/tire is visible from the side tho you dont want the tire/wheel to stick out past the fender cuz when your bumped (& you will be!) it would flatten the tire. I think I'm gonna be good on the wheel/tire to spring clearance. I will...

    Abody SBP 7&1/4 vs 8&3/4 SBP overall length

    Good info, thank you very much blu. with the pattern change obviously I wont be able to throw the rim on there right now till I get the rears swapped but I will measure as best as I can this afternoon & with the SBP 8&3/4 being a bit longer I might get lucky! thank you again. RR

    Abody SBP 7&1/4 vs 8&3/4 SBP overall length

    CORRECTION: my mistake, this is a BBP 7&1/4 going to SBP 8&3/4 and unfortunately spacers ain't allowed in the class. I will measure the SBP 15 x 7 wheels that I have, the backspace & post it later but it is deep. RR
  27. Rapid Robert

    Abody SBP 7&1/4 vs 8&3/4 SBP overall length

    is the end to end wheel flange distance pretty much the same for the two? I'm swapping rears & having potential wheel backspace clearance issues from wheel/tire to leaf springs. I am not in a position to measure everything right now. any thoughts? thank you for your time. RR
