My findings with different spinners and hex nuts used on my hubs:
AK 1106 had hex nuts and spinners, a different set of set of hex nuts I bought from AK 1093 fits as well.
Back in the days owners could order spinners "in the trunk" directly from Autokraft since the beginning if the delivered cars needed hex nuts to fulfill regional legal requirements.
Aluminum Spinners from TRIGO borrowed from Hobo's car (AK 1073) and a set of stainless steel spinners from
www.cobraracing.com also fit to my hubs.
The stainless spinners are made to fit 60s 427s, are equivalent to Shelby 3011R-L/R and fit to my car without any problem.
Cone aņgle on all spinners I tested and used was 60°.
It would be interesting if the spinners and hex nuts from Hobo's AK 1073 and AK 1450 are interchangeable !
