new old build 68 valiant

18x8.75", 255-40 rear 245-40 front.
Mines way different w/ a '69 b-body rear and drum brake spindles on front with now discontinued A.R. engineering early viper brembo caliper kit using 11.75" c-body rotors.
T-bars are easy enough to change later, from where I'm sitting it looks like you've got darn near all you need to get it rolling. good luck!
