Gooseneck help or ideas please!

[chicken1]

HI all,

I am looking into putting a gooseneck hitch into a 1972 Chevy C50, but the only problem I can see is that, the hitch needs to be installed in front of the axle. If I install the hitch in front of the axle, then I cant hook up the trailer, because I wouldnt have enough clearance from the rear of the bed to the trailer. I have looked at adaptors and extenders but neither seem very safe to me. Would it be ok to install the hitch right where the back part of the spring mounts (closest to end of truck) for the rear axle? I only ask that because if I was to do that, then the trailer would fit and have clearance. What do you all think?? Any thoughts or suggestions would be appreciated. Thank you and have a great day!!
