Dear Welder Series…
Any idea whether the center section will work with a 67-72 C10, and do any of the trans mounts fit a 4L80E?

Thanks,
Russ

Dear Russ…
Thanks for this note, Russell.  

Could you give me your frame’s outside and inside widths (driver’s side to passenger’s side) at the transmission insulator?  

…and the frame rail channel height at that point? (The actual frame size, not the height from the ground.)

I’ll see how the center section looks in those dimensions and get back to you.

Dear Welder Series…
Thanks Paul,

I’ve got the following:

Outside frame rail width:  34-1/8″
Inside frame rail top:  29.5″
Inside frame rail bottom:  29″
Frame rail height:  6″

Dear Russ…
The center section will be snug but fine if the rails are boxed corner-to-corner off of the upper flange. If the plates are “step boxed” it will give extra space for a frame mounted booster.

This is based on how the curved lower tubes transition to the boxing plates.

I hope this info helps with your planning.

Paul
