ok seems as though the tranny was a false alarm.
i could not find the TSB for the MC. was running short on time so mabey a more thourough search tomorrow.
MC size: 1 1/8"
Ya that TSB or what ever document it was that I found a while ago...was very specific to ford trucks and the MC size that when you find a situation like yours...they up the size of MC and that problem was solved...I just wish I could remember where I saw it. Doh!
Glad that tranny issue is false alarm.
Maybe see about a good 1 5/16" from a wrecker...see if that helps?
Lastly and this is something to think bout...having the drums measured for actual diameter and then taking the brakes to a brake/clutch shop and have the shoes Arched....they take and actually Grind the shoes to the exact arch or radius of the drum for a better match...
I am running out of suggestions at this point...flex lines just to soft has already been mentioned..but eh...I dunno...
