Is there any way to distinguish between the crankshaft/connecting rod of a 505 1a/b/c and that of a 505 1/d without measuring it (i.e. any identifying marks that may be stamped on it, or visible characteristics that are specific to the "d" version)?
To any former sachs retailers or mechanics: Does the number "07005" ring any bells? It has been found on the inside of a NOS box with a sachs crankshaft.
If there is no good way to identify the crankshaft/connecting rod without measuring it, What is the best way to measure its stroke? Thanks!
