Gearbox games No.1

Among my boxes of supposedly Electra bits, I have 2 different layshafts as follows:-

A: Length 6 1/8”; scrolls both ends; no lube hole; drilled entire length; end spline 1 1/8”

B: Length 5 7/8”; no scrolling; single lube hole; drilled one end to  1 ¾” ie to lube hole; end spline 7/8”

Looking at the 2 layshafts available in the NOC spares shop #041288 seems visually to conform to my A and is for early boxes, and #048153 appears to match my B and is for late boxes.

So the shorter one will be the right one for my Electra?

Cheers.
