I have a Toploader 4 speed out of a 1969 mustang 390 4v car. I purchased it for my ‘64 custom 500 to do a manual swap. I didn’t realize I needed a longer tail shaft. So up for sale is a Toploader with the data tag reading RUG-AD1 with close ratio, 28 spline. I am in need of a toploader with a longer tail shaft (27”) ideally with an HEH-D tag. Any other help or suggestions would be appreciated.
