OK, here goes .......
Grizzly,
I went with the "original" Kings Patent gate, as is OEM on their "improved Henry." It was actually the easiest to fit and required the least modification. Still a bit of a job. I was some shaky sweaty when I attacked the rifle with the hack saw .............. no replacement if I screwed it up. It's a real sweet heart now.
Flint,
You could open the side plate and install a '66 ladle, but, there is more machine work involved than using the gate for the Taylors Rifle. the '66 lifter could also be used, but it isn't flat on the bottom. Doesn't look at all right. Henry Carrier Block needs to be heavily modified to work as a side loader (I copied the one in my Taylors transitional). The '66 follower won't work, You have to have a "stop" for the follower. There is no shoulder to stop the follower in the Henry frame, so the spring just spits the follower into the carrier block (don't ask how I found that out
). Your stuck cutting the thumb button off the Henry follower (leave enough stub for a stop) and using it. I did order another Henry follower from VTI but I don't expect to ever run the rifle as other than a Transitional.
I also modified the carrier to run .45 "Squirt" so the magazine now runs a full 10 rounds for match play. This little rifle is hoot to play with. With 10 rounds, and no Henry "hop" it is a kick at a match.
You really have to be seriously nuts to do this mod on the fly. There is a lot of receiver to remove and if you get it wrong ............. I don't even want to think about that part. I musta been knutz!! I'll figgure ouot how to post pix. Its a neat little gun (it's still heavy, it's a Henry!!).
