Bob,
....question about the Osborne assembly manuals......you know pg 37 of the 1970 Electrical Assembly Manual that shows the circuit breaker being used instead of a fusible link has a revison date of
12-23-69 and says it supercedes 11-24-69 effective with CZY1-RD-5222222
my cars build date is June 1970
maybe assume that it might have taken several more weeks for this revision to show up on the plant floor...........so maybe the circuit breaker is correct for a 70 convertible build Feb 1970 on?
