You cannot. They are year specific so everyone with two fingers are selling necks from the 2 different size fork IDs from
(I believe and will correct if I am wrong) 1963 to 1965 and 1966 to 1973 calling them all Stingray necks because the average human is greedy and will exploit their fellow hobbyists to make every doolar they can from parts. Also I saw GTs58 posted about pre 66 not being marked.
Drop necks like 10 speeds/road bikes do not fall into this category since no Stingrays used them from the factory
Any necks after 1973 are not as desirable since the best of the Stingrays were no longer being made.
Not intended to offend anyone, but I am offended by the whole process.
I have seen guys selling brake straps for the 1971-1973 rear disc stingrays for insanely unbelievable prices. For crying out loud, it is the same cadmium brake straps that have been used on coaster brake Schwinns for a lot of years but the ones advertized for disc brake bikes were bringing 300-500% more for quite awhile until guys like me figured it out.
I started selling every one I could find for the same price as the ones advertized as coaster brake straps. Others did as well, I do not take credit for everyone finding out they were the same. It did need to be done though.
I have sold a lot of parts for bicycles, engines, motorcycles, cars etc but I always tried to be fair and honest about what i had and what it would fit. Otherwise I may as well been a used car salesman at a cut rate lot polishing turds and gluing bumpers back on.
I really don't believe you fit this category, and I understand wanting to make what you can in these hard times. Just please be considerate of the guy on rhenother end of the ljne. We are all in this together to varying degrees and a little help and respect now and them will really help the hobby.
