Just note that the hand wheel advertised on authentic classics & Pelican will not fit on early 230SLs unless you use a conversion kit that I think authentic sells.
SLS has the correct handwheel versions for early 230Sls up to VIN 002926, and a separate version for VINs 002927 thru to 012466. Later 230SLs (VIN 012467 -->) /250/280SLs use the handwheel as listed by Authentic Classics & Pelican
