Pintail Spreaders

How long are the spreaders on a Pintail? What is the material of construction? My boat came without spreaders, and I would like to add them to help support the mast.

I have a broken spreader and need similar info regarding the end piece. When I pickup my pintail, I will post length,diameter and description.

some pintails do not come with spreaders.

My 1976 Pintail has spreaders. They are 26" long aluminum tube. 1/2" diameter round that transitions to 12" square where it attaches to the mast. They are mounted at 93" from the bottom of the mast. See attached photos. There will be another posting by me because I could not fit in one.
