1966 CL77 sprocket cornfusion

[barnbiketom]

Hi all. long time lurker, now that I found a 66 CL77 I'm confused about the sprockets.
I need front and rear.
I HAVE ascertained the rear is 'big brakes" aka DLS and the bolt pattern measurement from mount hole to adjacent mount hole is

2 3/4 inch!!! correct?? but have yet to have any Ebayer respond with their measurements GRRR.. and they all look bigger like the 3 1/8"ones...

BUT The real problem i have is the deep/narrow spline stuff.
I cant figure if it is shallow or deep, and with Glaucoma its hard to say what i have, and what he sellers got...

The one you show is DEEP Spline.
It's warn out. .....................lm
