Watch that screwdriver across battery posts trick,...lol. Looking great man!!!! I have a nearly complete 68 D100 318 auto with dash shifter that will probably get parted out after donating some parts for my 65 D100 318 poly, 3 on tree, and 391 gears(open). I also thought of those aluminum case OD 4speed trans to get more top end. However in these old trucks, I think that a change of rearend gear ratios will prove to be more a detriment to local driving, with non-power steering and brakes it may lunge forward faster than you are able to steer it, even with that big wheel. The trans wouldn't have the same issue where first three gears are closer to original, not affecting taking off and steering as much. Also, lose the non-synchronized first gear for synchronized. I also have a set of those baby moons but haven't looked at them recently. Lots of stuff available. Just found 2 more trucks last week. My 65 is about to get the floor replaced with a good salvage floor I found for $45, I just gotta go get it. There are lots of high performance parts available for that slant 6 too. Just keep all the original stuff in case you ever want to return to original again. I have some decent front metal too, but shipping is a lot, unless we find someone going that way. There is a guy (Jim McGee in NJ) who made a nice video of cab restore for $20, I hear it was very well done too. Alan
