Dropmember with LS/4L65-E clearance issues - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have the Dropmember 3.tube, I guess now it would be called the Extreme Dropmember. I finally sat a motor and trans (5.3 / 4L65-E) in the frame and test fit the cab. With the frame rails flat on the ground I have the engine and trans tilted 5° to the rear. After cutting the floor for the high hump things still aren't clearing well. After finally getting everything trimmed so the trans clears the cab its now holding the high hump up off of the floor about 3/4". I also had to trim the floor some behind the high hump to clear the tail housing. I was just wondering if anyone else has run in to the same issue, maybe I have something assembled wrong. TIA.

Which year truck and can you post some pics of the clearances, including the rack to pan clearance?

Thanks!
