What determines which cars got the master cylinders with the lines toward the engine vs. toward the inner fender. Always heard it was a HEMI vs. big-block thing, but that doesn't seem to be the case. Early/late or plant thing; with b-bodies built at Lynch Rd., St. Louis, and LA? Is there anything on the b'cast sheet that would point towards one or the other?

I have a (February '70) '70 LA "E" built GTX with power disc brakes -
-- it has the bendix booster with master cylinder with the brake lines to the inner fender.

There is a (October '69) '70 St. Louis "G" built Charger SE with power disc brakes on Ebay -
-- it has the same set up
