Bulb socket question

[Rifter_Chevy]

Ok, im replacing all the wiring in my truck, literally all of it from headlights to tail lights.

Im going to replace all bulb sockets while im at it but i need to know which sockets to buy.

I have a 1984 pickup, i know the tail/brake/turn lights are 2057's i know the front sidemarkers and rear corner markers are all 194 wedge bulbs.

What i need to know is what are the front turn signal bulbs?

I think they were single 2057's per side however i have switched my front end to a newer bodystlye and now have the dual signals/markers per side not the single bulbs the stock front end had. I know i had to cut the original single bulb base's at the tabs to get it to fit into the dual bulb fixture, i have been running with only a single bulb per side and this is part of why im buying the proper bases and going to real dual bulbs per side.

what is the correct base for the dual bulb fixtures? is it a 3057?
