FLO pier (Ambermile?)

I bought one of the FLO piers a couple of years ago - red painted 10in tube with a nice level adjustable aluminium plate mounted on 4 steel studs. Very satisfied with it but have just changed from a 14in wedge and fork mounted 14in Meade to a 14in Meade ACF on a Paramount ME. I need to raise the base of the pier about 12in to have the OTA at the optimum height in the RoR observatory.

I have found a local fabrictor who can make me up an extension to put below the exiting pier.

Would anybody be able to tell me the hole pattern on the base. I do not think I can measure it accurately in situ as the base is well below the observatory floor. And I would rather not be unable to use the scope while the extesion is made up as it might be some time.

Well I got in touch with Arthur and he gave me the flange dimensions. A local metalworker in Plymouth is making one up for me for the reasonable price of £95
