I have not tried asking her. Might be the best idea yet.
OK; so got this from Manfrotto - Bogen 3051 is probably about 20 year old tripod, which they have zero parts for.
The suggestion is that you need a new tripod....the 055 is the comparable to the Bogen 3051. Our Manfrotto rep will follow up with technical support on the inquiry but it's a long shot. If you can email me: Helen@adorama.com with your 'phone number Dideo in the Manfrotto tech team will call you.
