[TR6] Farmall tractor clutch substitution?

["Theodore R. Stevens" <stevens@erols.com>]

This month's Grassroots Motorsports has an article on junkyard upgrades
(Boneyard Brigade, shopping for high-performance parts in the junkyard)
which states "A clutch from a Farmall tractor is essentially the same as a
TR6 unit".  Anyone know if this is true, and if so, *which* Farmall tractor
clutch? The endnote gives J.K. Jackson as the source of some of the Triumph
info.
