I'm sure someone else's memory is better than mine and can help, but I think there was a section on that in a soft cover book that is titled something like "Tri-five Chevy Truck.......? It has to do with repair and upgrading Task Force trucks. If someone else doesn't know, I can check tonight at home. I don't remember if Tom Brownell's(sp?) book has a section on that, again I can check that for you & let you know. Also, I believe if you do a search in this forum, you might find a link to someone has has done that and published photos. I am fairly certain some members of this site have done that.
