Hi Everyone!! I need to make a little modification on the speedo bullet that goes in my '55 Chevy equipped with a TH350. What I need to know is the thread size of the bullet. Thanks Danny
Buy a thread guage and work it out for yourself. Old threads get drilled and retapped so regarless of what anyone on here says it could be anything. Give a man a fish and he wont go hungry for a day, teach a man to fish and he will never go hungry. Sent from my SM-A105G using Tapatalk
Are you referring to the thread where the speedo cable housing retaining nut screws onto the speedometer drive? I don't know from memory, but I can measure one and post here later. Ray
The TH350 should use a speedo cable that is 7/8-18. Some good info here https://www.jalopyjournal.com/forum...d-th350-tranny-where-do-i-get-a-cable.308835/ Phil
@pprather Thanks Phil. I forgot about this until this morning....just measured one in my shop and was going to post, found your reply. Glad you posted since I dropped the ball...... Ray
I felt an obligation to keep my word in post #3.....in which I said I would measure and post the results. Not sure if your comment is intended to ‘console’ me or you are taking a shot. Regardless, I try to provide relevant information in threads where it is requested, IF I think my response may be helpful. Were it not for H.A.M.B. members routinely doing that, we would all be the poorer. Ray
