1970 Swinger 340 sending unit

I put this one in 3 years ago and it has been fine: 63-76 A-Body Gas Fuel Tank Sending Unit [3/8"] WITHOUT CALIFORNIA EMISSIONS
Only thing I've noticed different from the OEM one is the length of travel on this one is shorter so the gauge movement is quicker to full and as well to empty. So not as accurate. About 2 years ago until recently they did have an exact OEM style one made in the USA for around $90 IIRC. I don't see it listed now on their site however I would ask them as I think that would be the best option.
