Has anybody ever switched out a Starrett micrometer head?

I have a number of 436 Series Starrett micrometers, and I was considering buying a used, spare head. All of my mikes are ratcheting.

In the past, I have taken off the ratchet & spindle, but I have never removed the whole head. I would try to do so, but I am away from home for awhile.

I am sure that I could figure out the remove & replace installation, but I wonder which ratcheting micrometer head would fit my 436 Series mikes.

The micrometers that I have are long discontinued.

When I research it, I keep coming up with the part number 263RL. The R might stand for ratcheting, because they also have a 263L which is friction.

I took a close look at the part numbers of the component parts on the Starrett website. Most PNs match, but some do not match.

I wonder if the Starrett product engineers favored interchangeability over obsolescence for these.

Yes, because it is economical to just replace the whole mike. The used ones are very affordable on eBay.

My point exactly!
