you will have trouble with terminology....you say pancake engine, however, alot of folks use that term as a generic description of a "boxer" engine(horizontally opposed engine)....in a baja it is very likely that it is a type 1 *upright* engine...the "upright" describes the cooling system....the fanshroud is "upright" to the engine, whereas a type 3 or type
4 engine(commonly known as) are refered to as "pancake" due to their "flat" cooling system....your pistons sound like the typical run of the mill Mahle/Cima "90.5's"....rings are available from many online vw specific vendors...you need to measure your piston ring lands(the groove the rings reside in) to get correct rings due to there being two different sized top rings for your application....check here:
