Recommend cold crank amps?

If you don't mind interstate I go with Mopar from the dealer, made by interstate but look much better with the blue M. Retails for $125.00, dealer cost is $75.24 for 600 amp group 34 which fits most all older trays. Most dealers sell them on sale for $99.95 but find a dealer with someone that likes the old Mopars and maybe get a better deal. I run C-D-J-R parts dept and would sell for less for anyone with an old Mopar.
