Just purchased a 69 shortbed. Previous owner had dropped in a crate 350 and a new jegs auto tranny. The speedometer works but is not accurate. 85 on the speedo is actually 70 on the pavement.
I have done searches, but have not discovered any way to fix this. Is there an adapter or converter that will put my speedometer back to proper accuracy? I don't want to change the stock instruments unless I have to.
Thank you in advance for any help you can offer.
