Bearcat ejector housing swap

[goboom]

I see the Bearcat ejector rod housing (ERH) material has changed over the years...from
early steel to middle aluminum to later steel.

Leaving the much shorter Shopkeeper variation aside, I have two questions:
1) Is every Bearcat ERH easy to swap (early, middle, late) among the 4" and 4.25" barrel variations?
2) Also, are the ejector rods easy to swap?

Thanks, Goboom

Should be no problem with either. This is a "Colt style" rod I put on one.
