Thanks ChickenBalls. Dont need futaba if they wont work on MKS. Any help will be greatly appreciated.

I think they are futaba 25 spline, but making sure never hurts. I ask Amy, cause she knows everything, and all I got was ..I.. couple of the fellas here will know for sure. Bet one of these fellas would know @pawnshopmike @Terryscustom

I've read multiple time here that they take FUTABA splines. The new HBL380s have a new, larger spline.

Sorry if off topic to the 777s, but since you mention 380 arms, I know Thomas said a couple weeks ago that new arms were coming in soon. They may be in stock now (FWIW). The schematic on the site still shows the 25 tooth spline.

They are Futaba spline.

Just ordered a set for my 89 rebuild so I gota pick up some arms also.... Maybe I can avoid blow back with these LOL

Here is the what I have heard and know......The 777's 25 tooth like Futaba. This I know cuz I have used them. I have heard the x6 series is also 25 tooth. The HBL 380 and x8 series stands alone with its own special spline and larger diameter (even though they have a 25 tooth spline)
That is why you need the arms for the 380. Correct me if I'm wrong but this is what I've heard .

777's = standard Futaba, plain and simple.

Yes! Like Terry and the others said, they are Futaba.

Sorry for the slow reply, somehow I missed this alert.
