a buddy of mine has an old colt lower that has a screw for the front take down pin. he would like to know if he can change it to a push pin/detent style. this is a new one for me and i figured someone out here would know. i assume the question would be if the lower had a hole for the spring/detent right? TIA.

RIGHT!

If not it can still be done!  I had mine done at S.A.W. for 50 bucks or so!

MONEY WELL SPENT!

You're correct about the lower had a hole for the spring/detent but it also have to have a small pivot hole .250 DIA size for the mil push pin.

I converted a couple of Colt carbines with screw pivot type to push pins.

If it has a mil-spec .250" pivot pin (same size as rear pin) and has a raised fence around the mag release button, it can be converted to a captive pivot pin. If the hole is already drilled in the front end of the fence, then all that is needed is a new pivot pin, spring, and detent. If the hole is not there, it will need to be drilled.

If it has the large .315" pivot (with the two screw heads), then he'll have to buy one of the self-captivating pins:
