you are aware I have had many problems installing a sure grip in my 8 1/4 rear-end!!! In order to pass on my knowledge gained from this adventure and to help someone else avoid the same headaches, I have come up with the following. There are at least 3 types of housings for the 8 1/4. Two of them use interchangeable suregrips, they are the 1975 and later and the 1974 and earlier up to around 1968. This carrier "suregrip" uses a different size ID and OD bearing and so far will not interchange with the earlier mentioned suregrip! Now I an not sure which suregrip I need or if one was available prior to 68. No one seems to know. If anyone out there can add to my assessmets please do.
