   I used dorman 611-156.  I cut 1/2 off the shank of each with a sawzall to get the correct length.

	I talked with Chad Quella, the guy who did the run of reproduction turbocast wheel nuts a few years back, and they are no longer available. He did however enlighten me about how to modify the Corvette lug nuts which come drilled for 7/16" studs, rather than the AMC 1/2" studs. Here's what he wrote: "Here ya go... The demand for the lugnuts was initially very strong but the last couple years has dropped off to about nil. Also, I see another solution has become available and it will probably be less expensive for you. Look up a company called Ames Performance Engineering. They make Pontiac restoration parts, and they have made a lugnut that is almost right. It is for 78-81 Firebird snowflake wheels. GM wheels use 7/16-20 lug bolts, AMC use 1/2-20. So if you order the Ames product, you can then take them to a local machine shop and have them drill-tap them out the extra 1/16 inch to the 1/20-20 size you need." update - I looked up Ames Performance, and it looks like they are no longer stocking that lug nut. However, a quick search on eBay yielded this result: https://www.ebay.com/itm/1976-1982-C3-CORVETTE-ALUMINUM-WHEEL-LUG-NUT-SET/182191508676?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160811114145%26meid%3Da622c47c2c2643b9935930055198c260%26pid%3D100667%26rk%3D5%26rkt%3D8%26sd%3D173465667033%26itm%3D182191508676&_trksid=p2045573.c100667.m2042 Edited by 73Gremlin401 - Jun/23/2019 at 4:46pm

	Has anything transpired since the last post regarding these lug nuts? Found a set locally that I'm hoping to get for my dad's 77 Gremlin

	Back again - Got a set of the Dorman 611-248's (GM replacement 7/16 thread nuts referenced above) that I was planning to drill & tap for 1/2-20, however I measured their shank at 0.69" diameter. The shank bore diameter on the turbocast wheels I have range from 0.734" - 0.750" Are the turbocast wheels lug-centric or hub-centric? I feel like the diameter differences is too much, possibly even for a hub-centric setup. My backup plan is to get a set of the Dorman 611-156's (1/2" nuts with longer shank as mentioned previously) which have a 0.74" shank diameter, and just machine the shank shorter.
