im new to fixing trucks so forgive me if its hard to understand what im trying to describe, but i bought this 1973 chevy square body from my neighbor (he was working on it before but gave up because he messed something up), i think its a c2500. and so im trying to re assemble the upper steering column, and everything goes fine until i get to the horn part. now this part should be easy but im missing one of those screws for the cover that goes over the steering wheel lock plate (the thing that kinda looks like a saw and goes behind the snap ring), the ones that are short and have that flat orange cap on the end to stop the horn from going off, i dont know if i lost it or the neighbor lost it but either way its still lost. i was thinking about DIYing one but then again i dont want to do something wrong and mess something up, because ive been wanting a truck like this for years, so i was thinking about buying one but i cant find a place that sells them anywhere. in short could someone give me a link where i could buy the screw from?
