Hello,
i have aluminium pistons which didn't have oil holes drilled for the wrist pin in my 26 Roadster.
Can someone please post a picture with the aluminium piston with the oil holes drilled?
I am interested in the location of the hole, the number of holes and the diameter.
My intention is to drill the holes for the oil.

It’s actually more important to have the pistons honed to fit the pin. Most T piston pins are way too tight and/or the bores are out of alignment. Correcting that is more important than drilling extra oil holes. If you do drill holes, you will need to somehow de-burr the insides of the holes.
