I've noticed that there are a few running and driving rods up for sale for under $10k now and then. Mostly T-Buckets and other simple styles. I've been looking at ads, but I don't really know what to look for when checking out cars, what's important and what isn't, how to tell a good car from a not so good car. I know about cars in general, I'm 55 years old and have been doing run of the mill shade tree wrenching since I was in my teens, but I don't know the finer points of rods. Any advice about things like frames, suspension, steering boxes, bodies, etcetera would be very helpful. I have questions like is an original frame better than aftermarket? If aftermarket how can I tell a quality one from crap? Is real steel always preferable to a plastic body? Are some steering boxes preferable to others, and other questions about the fine and not so fine points of basic rod construction. Thanks for any and all help.
