this is what we did..if you have your old bimini you might be able to save it and save yourself some money..but it takes some work and inginuity..i pretty much did this myself..and told the auto uphostery guy to trim here the there and add a few things..it cost about $110 dollars to have it sewn and trimmed..but well worth it cause now we have a bigger bimini than you could ever have with a regular run of the mill tower bimini..so check out this pic of the boat we just finished a week ago
