Need help with cam chain tensioner

[Bevin]

It has been several years since I pulled my 1980 SG apart to change the cam chain, etc but abandoned the project for other "more important" stuff. I'm finally motivated to complete the job but seem to have misplaced the 4 fasteners/screws/bolts (?) that hold the base of the tensioner to the case. Are they bolts or screws? Is there anything special about them? Any info on what size they are? Thanks

74 up chain tensioners should have 6 garden variety bolts (6mm x 19 or 20mm) If I remember how to read a Yamaha part number. 4 Bolt tensioners were used 70-73.

Sorry, I should clarify - I am talking about attaching the rear tensioner bracket inside the top case not the tension adjuster.

That bracket uses two lengths of screws the left side is different than the right. From the factory one pair of the phillips heads are silver the other plain dark steel
