What diameter is a 784 torsion bar?

Starting to restore my newly aquired 69 RT/SE. Did search the archives, but could not find what diameter these are.
Thanks...

Read it on the end of the bar. Guess I'll have to take a closer look

Maybe the 4 is a 1

That's what I'm thinking

aren't CASTING NUMBERS different from SERVICE NUMBERS on catalogs by just one number up or down ?

one example, my 971 oil pan shows a 970 on catalog
