Its a 30-06 kit, I may just keep it that way. Its a Saganaw KitYou can create a wanted to buy post for parts you may need. The 308 conversion requires bolt modified for 308, a different booster(30-06 booster has a hole diameter of .72”), and cartridge guides. Top cover may need one part changed. Your bolt should be a 30-06, unless switched for some reason. Then it would be stamped 7.62 meaning the slot was widened to accept the 308/7.62 rim. It’s a larger diameter than 30-06, you can try sliding a 308 down the bolt face. 30-06 bolts are desirable to some members like me, I shoot mostly 06. The bolt needs to be milled for the denial island and KMP sear, lock frame & barrel extension also. Several here do the mods quite well. They should see your post and provide contact info.
You also should inspect your parts for who made them. SG or Saginaw Steering Gear is the most common, RIA Rock Island Arsenal, W is W estinghouse, and BA is, hmmm I forget, Barely Acceptable or is it Buffalo Arms? Use the search feature for more information. Buffalo Arms barrels are easy to spot because of small ridges left from turning. Pictures of your kit would be appreciated.
