Steering gear HELP

[phatchallenger]

I got a 74 Challenger with manual steering i replaced upper & lower ball joints,inner&outer tie rod ends,bushings, new shocks,had a alignment done but the when i turn left or right the wheel doesnt go all the way back to center by it self the wheel seems to stick if i driving and if i move the wheel a lil left it will pull left if i move it a little right it will pull right so im wondering do i have a bad steering gear box and is the box adjustable
The car has a 383 can someone tell me where the timing marks are i have look but i cant see any are they on the balancer or does the balancer have only a line going across it
Im new to Mopars this Challenger is my first Mopar but it wont be my last i had a few Camaros and a Mustang Fastback for years i told myself now the time to get a Mopar so im looking to you Mopar guys for some help
Thanks guys

Did someone adjust the gear box, could be set up too tight. Was it like this before the work was done? There should be a timing tab on the ft cover, look for it and post back the results. Did you put radials on if so the alignment cannot be done per specs.

i did put new bf goodrich radial t/a all around, the tag i will look it up tomorrow i just got back from a 600mile trip with the car so im kinda of tired and i dont think they mess with the box it was already like that
