"I think the lights on the 38 were bulbs originally and if they were changed to sealed beam there would be no adjustment other than moving the base"
Interesting.. I wonder why they were changed to sealed beam. Correct, I have none of those adjusters. Hmm.. I did a search on '38 truck headlights but its so long ago.. I cant find anything decent. I dont even know what was before sealed beam.. I thought it was lanterns lol. Gord I am thinking I would have to convert the lights to the link you mention to get them aimed or yes adjust the buckets somehow. I hate to replace anything from original but will look at both options. Thanks for the info on this guys.

Heres another pic of the truck btw; its getting there..
