I have the same issue- the stock folder blocks the trigger when folded and the LOP is on the short side for me...I wanted to use an AR tube with an SBA3 brace.. I haven't done it, because I'm not that keen on the solution, I'd like less than 3 pieces just for the mechanism...
anyway:
You'll need a new stock adaptor plate: make sure it has holes in the right place for the roll pins ! the .556 version and the 7.62 versions of the pistol are different
Compatible with ACE-brand stocks and folding mechanisms, the KNS Precision Galil Ace Stock Adapters are manufactured with a ‘pocket’ for use with ACE brand stocks/folding mechanisms WIT…

Then you'll need to find a right folding mechanism to bolt to that plate: ace make some, but the ones with a built in buffer tube adaptor all fold to the left, so you'll have to buy a right folding hinge then add an additional buffer tube adaptor...
