M1 Tunnel Ram Top Plenum Volume Reduction with Photos

Do you have the large or small top tr1
Small top I think. Haven't looked at it in a while but I'd say it is smaller in volume than the one in this thread before he cut it.

Edit...
I may have misspoke. Could be a TR5. I think this is a pic of it before I picked it up but its stashed in the attic at the moment.
