this has been a long trail, the path sometimes lost/found several times. maybe 5 years ago i began thinking about replacing my 4.11 ring/pinion with a "larry jackson" 3.5 set. i thought and waited etc...$900, then $1000. i called larry. "never more" quoth larry. now what? i inquired through my local vcca ps region "tappet and clatter": no help, i chatted this board, and finally i put in a "wanted" notice in our fine "g & d". i got two reponses, tex. and alabama. i spent $525 plus 1/2 the shipping; total, $540. gears and gaskets arrived soon after, new and perfect, never installed. installed now. what a grand difference! my '30 coupe glides along so easily now. the extreme low end torque has been tamed and the higher gear ratio allows me so move along at 50 to 60 without strain; less apt to be rear ended on the faster roads too. oh happy day! jim
