I could use some help!! I want to replace my fiber cam gear with the aluminum one on my 1959 235 cu in chevy engine. All the online parts listings show models covered up to 1958 and then for 1960 but no 1959. Was there a change in the crank gear or some other issue that causes the 1959 to be unlisted. Sure would like to know how I can get the right part. I called parts geek and they couldn't help. Any advice would be greatly appreciated. Thanks
