7260 to 7290 conversion

X3 on the 1350's That way it will be done forever.

I ran the 7260/7290 conversion on my 65 Coronet for years. Cars weight was around 3600lbs and ran Hi 11's. The conversion isn't junk but 1350's are piece of mind.

Torq and heavy cars are the downfall for smaller u-joints.
