3/8 sending unit $$$

www.partsgeek.com sold me a Dorman sending unit with the ring and gasket. $59.23-Check it out! p/n 692-152 is a 5/16 outlet.
Also bought Dorman 1.125" front sway bar with everything needed for installation (my car doesn't have one). $115 p/n 927-196
We'll see what the quality level is when I get them. Bought some Dorman stuff before- was happy with them.

I'm sorry to have to tell you. Dorman has been Chineseoated just like everything else. I bought some of their acorn lug nuts when I put the 'Stang wheels on the car. Just about all the end covers, which are cheap tin pressed? into the nuts fell out. I took them back and got a bunch of guff from O'Reallys, and basically, finally gave up.

Can anyone answer, what might be MORE important than the quality of a lug nut?

Just like so many old U.S. manufacturers, crap.
