Haven't seen any 50-series 14's in years---biggest 14" I know of is RadialT/A 235-60x14. Conversion would be 235-50x14. Might try Coker Tire in Chattanooga, TN. Good luck, let us know if you find some (I have a set of 14x9 slots stashed away...)
Got to clean out garage and raise some cash- have a set of 15x9 & 15x7 Fenton R/T's (Look like Centerlines) with 295-50's 60% tread and weather-cracked 205-70x15's. Have all lugs & centers. Asking $550 for everything.
Never been on a GM, like to see 'em stay ona Mopar! Thanks!
Welders are like any other skilled trade- some guys take pride in their work some don't.

(and yes, I'm a welder, among other things...)
Measure the distance (inside to inside) between the 2 lips where the tire beads up.
The only dumb question is one you don't ask and then later wish you had...
