Well, here's my Fir necks that I've been practicing on.
And from the side:
Going from right to left - the right most one is the 'banjo' neck, and the 4th one is all the way on the left. The latest '59 roundback pucks are real close: I was shooting for .95 at the 12th fret and .85 at the 1st fret the 4th neck ended up 1" and .87" respectively - so, I'll have to sand off about .02" off of the front puck and about .04" off of the rear puck. The nut width worked great - these pucks are for a 1 11/16 nut - that worked great.
