Hi folks, I have a 75 Oday 22.Looking throught the D&R Marine site I saw a "Mast Step Casting". It appears to go on the bottm end of the mast and possibly sit on the tabernacle. Or, assuming I need it, does it just rivit to the bottom of the mast and you install the tabernacle pin and it swings up on the pin when raising the mast?I have not raised my mast yet and was wondering if I need one of these mast step castings? I have the Tabernacle Pin. I always wondered if there should be more support at the bottom of the mast than the pin.Is the weight of the mast on the taberacle pin or sitting on the tabernacle itself?Help!!!!!Thanks in advance!Jack
