Lostmind; I just saw a 1980 KD catalog on e-bay, they had you KD 2377 wrench, ad reads;
VW axle nut wrench K-D 2377
removes "frozen" VW axle nuts, 36mm, strike with hammer to break nuts free.
A 1/2" square opening on the tool allows mechanic to use a racher drive or a breaker bar.
sturdy forged wrench is heat treated and plated.
