'64 Dodge longbed clutch question

Probably a 10" as the Valiant passenger cars used a 9" and I swapped a 10" clutch and pressure plate from a into a slant six Valiant when the parts store said that was all they had on hand and overnight delivery was still a decade away.

nSurferx queried:

For what it's worth, the Hays and Ram Clutches say that from '69 thru '83, all D/W-100 thru -350s used an 11" setup. However, further searching showed an exact application on the Luk website

where itshows you have a 10" cover assembly with the disc being 9¼" diameter.Bryan

Thanks! Now that is my 'to do' list the first thing for my '64 Dodge.
