The ONLY correct space saver will be a B.F. Goodrich.I've seen guys sell the 77-78 Volare Goodyear space saver on Ebay and saying it is for ebody's and this is incorrect.Early model types 69-70 production will have old numerical tire size 7.25-14 or later which will be your letter sizes E,F,G.78-14.Hemi's should all be 15's and are extremely rare.Vin for this is on inside of rim.Vin will be on outside of the rim by valve on the Goodyear type.
