Need help in finding out which tunnel I have? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I need to order some new carpet and I don't know if I have a low or high hump tunnel. If some one can measure there's from the floorpan and let me know, then I could find out which one I have. My camera isn't working, so I don't have pics of mine. I'll go out and measure mine and then I can order my capet.
Thanks Mike

Does it bolt in? high humps are always bolt ins. Ill go take some pics for you though.

As mentioned above, low humps are a continuation of the floor pan (part of it), high humps bolt on to the floor pan.

Here you go. The yellow one is a high hump and the blue is a low hump.
