Washers - NAS1149F0 vs AN960
OK, I am confused.
In Van's instructions (Section 05-33) it clearly says to NOT substitute a AN960 washer for a NAS1149 washer because the NAS washers are manufactured to a higher tolerance but when I try to buy NAS washers from Spruce they offer the 960 washers instead.
Is this a concern?
