Is this the pitman arm that I need to fit on a 83 CJ7 power steering
box and accept a 3/4 ton Chevy TRE?

5352278 PITMAN ARM, SJ POWER
(partsmike.com)

Thanks,
Dan

Seeing SJ power I'm assuming that's a full size Jeep pitman arm. If my assumption is correct, then yes it will accept the 3/4 ton Chevy TRE.

is that the right one i need one too
