On my '6, I had no problem using the spin-on adapter, but on my '3, i just can't bring myself to replacing the original parts. The old Purolator canister has been on there coming up on nearly 60 years, now. I would hate to separate them.
To answer Marla's question, I find it easier to pull off the front tire for a little better access; still, a messy job to be sure. But for a once a year chore...
Looks like a '60 Pontiac in Marla's avatar.
