OK men this woman needs your advice.... I have a 1970 Aluminum Orlando Clipper. There was a pedestal seat mounted on the front bench seat but my chubby fishing partner with his weight broke the rivets that it was fastened with. There is no access to put bolts with nuts under the bench seat. Everyone tells me I have to have someone cut an access hole to be able to put nuts on the bolts but I would think that would weaken the bench seat. Would blind fasteners or well nuts be strong enough to hold and support the pedestal seat??? This boat has so many holes I hate to put any more in. Thanks for your advise!!!!
