even the diesels were provisioned for it...

I heard tell that the reason why it was left on so long is that the thread of the bolt was the same so rather than turf all the already made up pullyboss/crank nuts they kept using the crank nuts till stocks were gone....

by then someone had worked out that the crank handle + crank boss was a usefull thing so it was kept in production untill compression rates rose so high that cranking was near impossable for a normal person.

my 93 disco had a crank boss on it...
