I purchased 2.0 liter rims for my '74 and I am trying to buy chrome lugs for them. I see many different lug sizes for sale and I am not sure which ones to get. I know that I need the ones that are round tapered, and I think I need the ones that are 38 mm, but I have seem some that are 39 mm and I want to make sure I buy the correct ones.

Thanks in advance.

1mm in length won't matter. 1mm in diameter would really matter, but I think that the diameters only change in 2mm increments anyway- 10mm, 12mm, 14mm, up in the bigger sizes.

Welcome!

14 x 1.25 thread. use the one listed for Porsche alloy wheels. I think it is 38mm long. ball end taper.
