I have a 1970 Ford XL convertible with a swapped 460 and I have a steering issue...

when I steer to the right it feels real hard, just like it would run without fluid and when I steer to the left it is normal and at a certain point it all the sudden steers all the way to the left by itself!!!

What's going on?? pump, gear??

It has enough fluid. Has been driven without fluid though for a while before I bought it!!

help! any ideas?
