Transmission to Radiator Lines

[Kisner]

The transmission to radiator lines on my 68 coupe (C4 transmission) are badly bent and not routed properly. As a result, when I turn the steering wheel to the left the power steering cylinder is hitting one of the lines. I bought a brand new set but here's my problem - can't get them loose from the transmission. Easy to unscrew from the radiator, but how in the heck do you get a wrench in those tight spaces to undo the fittings. I don't have line wrenches but can easily buy, but don't know if they'll do me any good since I can't figure out how to get the wrench on other than at an angle. Would be easy if I dropped the transmission, but that's not an option for me in my garage. Anybody know of any tricks or special wrenches to get those fittings loose?
