Travelette Cummins Swap - Motor Mount and Positioning

I am trying to shoehorn a 12valve Cummins into a '73 Travelette 1310. When I acquired the truck, it appears that a previous owner had welded in a non-stock crossmember, but the seller had no information. Does anyone recognize the crossmember in this photo (below)?

Assuming that crossmember isn't already fit for a Cummins, I need to figure out how far back to place the engine. For those of you who have a 6BT Cummins-swapped Travelette, how far ahead of the front axle centerline is the front of the engine block? Otherwise, which cylinder lines up with the axle centerline? With the cab already off the truck, it's really hard to guess where to put the new crossmember.

I've got a Travelette, but it's still got the stock engine. What transmission is going behind the Cummins?

That front cross member with the 2 holes was right under the damper wheel of the stock engine. If that helps. I think your going to need to set the cab and front bulkhead on as I don't think there are a lot of cummins swapped IH's out there.

That front crossmember with the two holes is original. It's the big honking one that nobody seems to recognize.
 
Here's a link to our 1967 1100B that my sons put a Cummins in a few years ago. The position of the engine in the chassis was around 5" further back from the axle center line than in the '94 Dodge Ram that it came from. Basically, the engine needs to be set back far enough so the oil pan sump sits behind the tie rod on the back side the axle. There was just enough room in the '67 leaving around a 1" space between the rear of the cylinder head and the firewall. My sons made the motor mounts that did not require a crossmember, there are pictures of them in the link. The Cummins makes 440HP and 1100 foot pounds of torque at the rear wheels and there have been no issues with those mounts or the chassis itself, it's all good. The engine sits down in the chassis as low as possible with the radiator hose inlet housing on the passenger side of the engine around 1/2" above the frame leaving just enough room for the rad hose and a 1/4" gap or so under it. The front frame reinforcement that is on an angle on the drivers side had to be notched for the fan. You are welcome to ask all the questions you want.

My sons and I started this build in April 2021 and had it roadworthy by mid July of the same year. This is our first build, together we figured out how things should be done and my sons did all of the work. Since then we have made a few performance modifications and recently reached our goal...
