Swim Platform Install Help

[jdooley]

Hi, Brand new to Forum... I have an 85 Larson DeltaConic and wish to install after market Swim Platform, as there are the pertruding styling/floatation humps on the stern of the Larson model, it is not clear to me how to install a typical elbow and platform type Swim Platform. Any ideas? Larson accessory books? pictures?
Thanks for any help.
