well  we purchased a  1991 cummins 12v with 140,000 miles on it and are beginning the conversion process.    found out we needed a govenor and our friend of many years  (over 30)  who runs a  diesel shop  wants  $1700 for that ...    this thing better turn out  great  cause  its costing a gob so far..

we've heard since that  Pensocola Diesel is the place to go ... didnt have the info soon enough.
