I order a triangle stock with 4.5 pin to swap onto my PSA 74 that has a solid stock.  I take it I just bang out the pin, add the triangle and bang the pin back in?  Anything I need to be aware of.
?  Should I remove from the top or bottom?  Or it doesn't matter?
Thanks.

You remove the receiver cover and drive the pin out from the bottom to the top. As with all things AK, fitting may be required to allow the new stock to latch open.

Trianlge came today, but the PSA pin seems too big?  I thought these were 4.5?  Or I'm I suppose to drill the hole bigger?

Newer russian and bulgarian spec is actually 5.5mm.  Call PSA and ask them what they used before you start drilling.

Took care of it yesterday. Ended-up drilling a 3/16 hole in my triangle (closest I had to the pin diameter).  Worked like a charm.
