Need a year for vintage steel

[cudarider1]

Thanks Don and Mark, Like you said my next pan was to swing by my LBS and see if they could measure. to be honest, since the A2E showed up yesterday my focus seems to have shifted toward thta so the schwinn is put back together exepct for the seat, post and the drive side LX crank is missing, I threw on my xt from my defunct A2M to take it for a quick ride so I'll probaby hang that up for now and throw the cuda on the workstand. Thanks for all the help, Once I get a seat and post I'll throw up a picutre.
