There are no ejector springs. Just two extractors with a right spring. Be thankful the thing extracts(assuming it does) and is a 66B. Gunparts wants $10.40 EACH. The extractor for a 66A is $5.30 more. The right spring is $1.40.
Take off the extractor spring clip, remove the right extractor and change the spring. Assemble in the reverse order.
