Id be interested to see any Info ya have on these that ya can email or
whatever or links to sights concerning them I have two one complete one
missing OD shift solenoid (anybody have one layin around the shop) just met
a guy that said he sold one on and auction sight for $600 that was also
missing the solenoid . I plan on puting one in my 38 1/2 with slightly
sooped up 235 and may put the other in one of my panels or sedan delivery .
I found a floor shifter in one of my piles of junk that may work with one of
em the other i think im gonna use stock column shift setup the biggest
headache apears what to do for a clutch/brake pedal setup look like the
stock setup in a 57 PU may work but not for sure yet. want use a 3:73 Rear
out of 70 Chevy pu or somethin similar so i can use my stock wheels on the
381/2. What kinda Mileage can I expect out of a setup like this. as Pump
prices aproach $2 a gallon it gets to be a bigger concern everyday.
Thx Jay Baker (Jays Classic Truck Parts)
