Having 2-3 shift overlap - Thinking of switching from 4.2 apply lever to 3.8 - Any Other Thoughts?

Thanks for taking your time to help explain how and why some of these work together. I pulled the accumulator to verify and there are no springs and has the blocker rod. I'm not 100% positive, but I think I remember adding the additional springs to the front clutch pack for 15 total. I'd rather not open up that area up at this time if I can avoid it.
Is there a particular 2nd gear servo I should get?
Here's two options I was able to find.

Part number 22905EBADR is the one from A&A that you want. It’s $145 compared to $165 from Cope. The only difference between the part number I supplied and the one you have pictured from A&A’s site is the one I supplied has dual rings over a single ring. This is for better sealing when this servo is applied. Chris Andrew’s should also have the A&A servo in stock.
