pfarber,
I plan on leaving the 4 speed in it, 40-45 is fast enuf in these old trucks. The closest interstate from here is 60+ miles away & people are pretty patient around hear.
I haven't found much info or even pictures of these trucks. I did look on eBay and found a lubrication chart for the AFKX compressor truck but haven't forked over the $75 to buy it yet.
Thanks
Steven
