T Bar size

There's nothing hard and fast except that 340 cars had the .870" bar and 383/440 cars had .890" (I think the 67 383 cars may have had the .870" bars, but don't quote me). 318 cars could have .850" or .870". the larger bars came on cars iwth the handling package or AC. Slant cars usually had .830", but could have .850" or .870" depending on options.
