Help Needed: Help me figure out if this is a good donor for BBSHD

[geosped]

I could use a little help. I found a potential candidate for my e-bike BFANG BBSHD mid drive kit. I've been doing a lot of research. I found this bike on FB but the owner doesn't know what year. He thinks it's a 2010. But from all of the looking around based on where the rear suspension shock is located I think it's a bit older. Could not find this color anywhere or info that would help identify what year it is in hopes of identifying what type of BB is used.

According to the add it's a 2010 Specialized Epic FSR. Also another potential identifier it looks like the bag is covering up the word "com" but it's probably comp. So does anyone recognize this bike?

I'm trying to determine a couple of things.
1) What's the BB length? Probably 68mm as this looks like a standard cross country bike. Will measure on site with a caliper.
2) Is this a PF BB or PSA (Threaded) BB have no idea but from what I understand bikes made in 2012 or newer are typically use press fit BB.
3) Is there more than 2 3/4" from the middle of the BB to the frame. To ensure chain ring doesnt hit frame or motor has enough room to clear the BB.
4) I will take with me the Luna WolfPack battery template cut out of carboard to see if the battery pack will fit but based on this particular frame that should be no issue.
5) I plan on bringing a set of digital caliper to take additional measurements. What am I missing.

Specialized bikes are known for having a bunch of "Custom" components built for there bikes so this concern's me a bit. Especially if they use non standard BB's etc...

The chainstays seem to flare out and could make it difficult for the motor to nest against the bottom bracket. This might require a wider system and spacers if that's feasible. Also, a "dolphin" battery may not fit in the triangle. Better measure first.

Here is what I found out:
2005 Specialized Epic Comp Disc It has an ES-30 Bottom Bracket.

I printed the Luna Battery Template and the battery fits fine with some room to spare. The battery should be no issue. Bottom Bracket is not press fit. It's a ES-30 appears to be 68mm and the spindle is 121mm. I'm attaching some pics. I would appreciate if anyone that's done one of these has insight.

Thanks in advance.
