Nope, what I had to do was make 4 holes bigger in the older PS 85s. Its the holes where you tie off that you need to increase. Other than that the new grommets work.
Nope. Most of the b/g fits except for the 6,7,8H holes (same for the 6,7,8T holes with the strip). You -could- modify the b/g at these holes only and make them fit.
