Man I’d swear that was my neighbors old truck when I was a kid, small ranch by my Dads place in Larkspur. Haven’t seen that truck since they sold it when I was 17-18 (just one of a dozen squares I should’ve bought and didn’t) but it has to be the same truck. Bone stock ‘79 K20 custom deluxe rubber floor mat truck, 350/465/205, don’t remember if it had a 10-bolt or a 44, but it had the original bright yellow paint on it just like yours. Maybe look through your old registrations if you have any, or do a title search if you get bored one day. If you find last name Neilson in Larkspur, that’s it.
Anyway I like how you’ve built it, it’s a cool truck
Saw it for sale recently, what’s up?
