Hi Tony
Looks like a fun vehicle to drive and enjoy. I had just finished reading another thread Engine Conversion
http://www.mapleleafup.net/forums/showthread.php?t=1082 and some of the thoughts are echoed on having vehicles that we can drive and enjoy is the best way to preserve them.
I always explain anything that is not stock or original on any of my trucks as being "field modification" done to make the truck meet the requirements of its currant purpose. Or use the phrase locally supplied body.
So drive and have fun.
Cheers Phil
