yes, the 3800 is a 1T [5.14 rear] and the 3600 is a 3/4T [4.57 rear], and a 1T would always have the driveshaft e-brake [lever near the shifter], but a 3/4T could have been equipped that way as well .... yes, a 235 was the standard engine for '57, with the 265 [or 283] optional .... can never have too many trucks - if ya got enough money to support the habit
