How many of you 'old farts' drive with the obsolete 'Columbia' two speed rear end ? I have had two in my 50 year history of driving my Ford Model A's. I like my current Michell over-drive much better for a number of reasons.

Ignoring the conversion of the V-8 Ford 'Columbia' "over-drive" rear-end, which was the rage in the late '30's, '40's and 1950's, the later 'over-drive' units were primarily Volvo conversions.

Then awhile later came the Mitchel Over-Drive unit, which now seems to dominate the current market place.

Of these later two (Volvo & Mitchell) over-drive units, how many of you have Mitchell's and how many have the older Volvo's ?

What are your 'selling points' of each, and what are the negitives of each?
