Swap V8 into 292 6 cyl frame during 4x4 transformation

I am looking for an Accurate measurement based off of a common frame location in order to mount a small block V8 during my K30 transformation. The frame is a C30 that had a 292 6 cylinder. I have made the straight axle swap, but now I need a measurement, as the holes on top of the frame are different when comparing my V8 sb crossmember. Ive located the holes for the bump stop on the C30 frame that appears to be the same as a K20 frame. The measurement I am looking for is the distance between the bump stop bolt (red arrow) and the front V8 motor crossmember bolt (green arrow). This picture is from a 1968 K20. Currently, this frame is buried in over 2 feet of snow, or Id measure it myself. Your help is appreciated.

I have a K20 at the house with the front clip off, when I get in from work I will get pictures and a measurement for you. Do you have V8 4x4 crossmember for the conversion yet?

Here is the measurement from a 72 K20. The tape is on the top of the stop bolt not centered on the bolt.

Thanks for looking into it. I do have a V8 crossmember. It is the one pictured.

How far forward is the center of the front crossmember bolt from the center of the stop bolt? 2 plumb vertical lines must be drawn based on the Centers of the two bolts, then a measurement made of the space between the two vertical lines. Sorry if I didn’t express my question better on my initial post.
