Still, regardless of what is used at the inboard end, the $25 arm does have the eccentric bolt and washers and the tabs for them to ride against, so it's still a relative bargain for what functionality I'm looking to gain. Since no one has apparently used the Ultra-Power brand, I guess I'll be cutting edge again. lol

The OE arm uses a solid rubber bushing. The SPC/Moog/8 other brands use an enclosed spherical bushing, that is why they are illegal in STX class. The Whiteline arm is the same arm, with the spherical bushing pressed out and solid "elastomer" bushing provided.
The ultra-power arm appears to be a replica of the SPC part, spherical bushing and all. Just noticed the picture, those cam plates are going to be a bitch, flat sides on a eccentric don't work very well.
Moog/SPC/et al
Ultra-Power!
