Question on Celestron Ultima 8

I'm the guy who recently purchased a very nice Ultima 8. ITS BEEN CLOUDY AND RAINY ALMOST EVERY DAY SINCE GETTING THE SCOPE! sad Figures...

Anyway, my question. The original owner upgraded the finder scope bracket with one that has six sets of set screws for adjustment. The original bracket is included. The new bracket is held in place by a vixen dovetail which is held in place by the screws that hold the rear tube end (endcap) on. These screws also go all around the rear endcap with a screen every inch and a half or so.

The finder scope is placed a bit too far to the left which interferes with the knob that operates the declanation clutch. There are a series of hex heads around the rear endcap that appear to hold it (and the finder scope dovetail) on.

I really need to move the dovetail bracket two screws over towards the center. Is this just a matter of removing the two hex screws and one by one moving them over?

Proposed procedure: Remove two hex screws holding the dovetail bracket on.
Remove dovetail bracket
Remove one of the screws where the dovetail needs to go
Replace one of the hex screws where the dovetail used to go
Remove the final screw where the dovetail will go
Replace the final screw where the dovetail was
Re-attach dovetai

this procedure would minimize the number of screws out at one time. Also, do these screws hold anything else besides the rear end cap? Anything that I should worry about?

Are you sure the screws in question really are ones that attach the rear cell assembly to the tube? I'd doubt that. Typically finders/dovetails, etc. are attached to the rear cell and corrector assembly by pairs of "Accessory Screws." If that is the case, there is nothing to fear. Might have a local C8 toting club member have a look at your scope.
