If I remember correctly the older Mopar V-8s had the same base as the common Ford filters they have been using since they started using spin on filters in the mid 50's until the 80's or 90's.
Back into the fog of days gone by..... that sounds familiar.That looks like an extra capacity longer oil filter.
Some folks don't think much of the current crop of Fram oil filters.if someone has this kit converters, what do you put as oil filter
