Manav,
I have a similar problem and used the solar noon transit to align the mount on the meridian - mark the feet position for the next time.
Set the altitude with a spirit level and cardboard template.
Final tweak if needed during a drift alignment.
I have a good site for the position/ timing of the sun’s position.
I’ll update when I can.
