Hi Jim
yes this information I am also aware of BUT what was change !!
I had a look at my early 230sl (chasssi 24) and a 250/280 sl etc I had in the shop ALL manuel set up
I must say I am blind, I cannot find the (tunnel change) that the records refere to in the books
By the way Jim The 190sl number 19 is soon on the road i think 1 month more and we are ready
it seams we have almost the same taste in cars .my first classic was alos a Tartan red 69 mgb 5 spd.
regards
Marek
