Great thank you,
Now to get the right part #'s
What I have so far is from here
http://jan.eaglecreekobservatory.org/focusermod.html
which are
(2 Torrington NTA-815 1/2" thrust bearings and a TRA-815 thrust washer) but think these might be American part numbers and would like to confirm are these the same part numbers that I can buy here in locally.
Cheers
