How many sizes are there for the torsion bars. Or are they all the same.

The better questions is what do you want to achieve handling wise with your car. The bars can range from .88" - 1.18. The aftermarket has created many options for improved handling.

Also '62 to '72 had different color paint markings on them. "Chart at the end of this thread" that I posted earlier.

67 318 you would have the next to the smallest size usually .86 Big Blocks may have had .88 unless you were a station wagon or cop car, or trailer tow, etc
If you are shopping pick a part look for a wagon with a trailer hitch thru 72
wide wheels and radial tires need bigger bars to keep the tread flat on the road
bars are available up to about 1/8- usually 1.24" bigger bars would be larger than the hex (but its been done for road racing)
1.1, 1.030 .960

has spring rates for some bars
recommends 200 lbs + for today's street
I remember we used to shot peen them then coat
BTW some short wheelbase C body Dodges and Plymouths use a 44 inch bar which can be made to fit in a 73 and up B

anyone know what the AAR cudas or the TA Challengers used
I had moved over to AMC by then
I think they had to remove the crossmember to get the big bars in as they would not fit through the hex
I can remember having to loosen up the front a arms to get some bars in but I can't remember if this was for Road Race or the little bars for drag racing- keep that in mind if you find they do not want to go in the crossmember- or you might have to take the rubber bumpers off to let the a-arm drop down a little- shocks too
I forget- remind me when you get that far
