I picked up an "83 N5.0 and it has diamond wires. I'm wondering if their stock. The top attachment is on the front of the mast and is a single point attachment. The spreader is a straight bar and looks to be in the correct position. The bottom attachment is single with a turnbuckle. The wire is slack to the point that I can squeeze them together about 20" above the turn buckle.
It seems to me that the mast will invert or bend backward under load. I guess that it may just bend on its small access w the slack diamonds.

Anyway, is this a stock diamond setup for the 5.0?

Also, I have a "76- 5.2 and the wires run from center top to a straight spreader, and to center at the. Ottom attachment with a bottle adjuster at the bottom
