Need 65 Barracuda info ** Updated **

As a matter of fact, no Formula S was factory equipped with an 8 3/4 as standard equipment until the 340 came out in 68! It was an option starting in late 65, so Joel is partially correct!!

And a note to the OP, take a pair of calipers with you and measure those torsion bars, not an easy or even thought about swap!! If they don't read .870, they're not the big bars and probably not formula S!!

Agree. The factory issued a letter to dealers around mid year to replace the 7 1/4" rear with the 8.75 on a warranty repair. Mainly pertained to the 4 speed cars. NHRA followed suit by a rule change that allowed the 8.75 rear in the 65.

I forgot to note that there's a copy of that letter on the D Dart site.
