4wd 4sp trans tunnel

[jasonda]

I need some help from you knowledgeable people about a trans tunnel. I have a 68 auto on the column cab that I am placing on a 4wd 4spd manual chassis. I was able to locate a local 70 model 3/4 ton 2wd manual trans cab and chassis that had a good tunnel in it but I am not sure if this is the same tunnel as would be in a 4wd manual truck. Can someone help me and let me know if this is the correct tunnel or do I need to find one specifically out of a 4wd manual truck. Thanks
