65 Barracuda Lug Nuts

[eengledow]

I bought a new set of chrome lug nuts - Rock Auto indicated 7/16" / 20 was the right size.....they don't fit - they are to small.
What is the correct size?

if you have the original axelshafts with the small bolt pattern 5x4 then 7/16" / 20 is correct.
Maybe replaced with the big ones and 5x4.5" then the thread is 1/2"

OK, so I measured the bolt circle and they are indeed 5x4.5"

Does this mean that the previous owner changed out the rear end....it does have front disc brakes, so I know those are not original.

What year would the donor discs and rear end been? or range?

Are the 5x4.5" thread size then 1/2" / 20?

Either that or drilled the axles for BBP. Without pictures, there is no way to tell what you have.

No way to know without pictures. Could possibly be anything, but I changed mine over to 73 and later A-body BBP single piston.

Are the 5x4.5" thread size then 1/2" / 20?

Yes.

possible too that there is on one side RH and on the other LH when replaced from a later mopar. check the Threads accurate!
