Not a lot of selections.. I bought a set of reproduction shocks for my 64 1/2 that look correct, (minus the stampings), and the ride is great and comfortable. I might end up going with the tried and true Monroe-matics as they are quite affordable, ride nice, and look close to the originals. But, waiting to hear what others have found.
I also see that Gabriel makes a standard shock sold through Autozone for $20 each. I will say I put a set of Gabriels on my 71' F100 but after 5-6 years, and not many miles, they were shot.. Not the quality of the Monroes.
