Hi Magnus and welcome to the Stovebolt Page! We have some other Swedes on the site so you have some friends here already!
Wow... they didn't leave you a whole lot to work with, did they?
What's there appears to be solid, though
If it has an engine, and the engine is original to the truck, then the engine number will tell us a few things. Look for the distributor. Right behind the distributor is a flat surface (where the dist shaft goes into the engine). On that flat surface should be the stamped engine number.
Also, to the front of the distributor and low on the block will be some casting numbers -- if you can tell us what those are, we can probably tell you more. At least what the engine is, anyway.
What are your plans for the truck? Looks like it would be fun to cruise around in just like it is (well, with tires and a seat...
)
Tack och välkomna!
John
