Trans floor tunnel questions
I have a 70 4x4 with a two wheel drive cab. The PO just hacked the floor to make the t-case clear. I got a 4x4 trans tunnel for a blazer and it is way too short. Do I have the wrong tunnel or are Blazer and pickups different?

Re: Trans floor tunnel questions
If it bolts in, it should be correct for a 4x4. The holes in it may be for different applications, but the height should be right. Burb, blazer, and trucks were the same i believe.

Re: Trans floor tunnel questions
Height is'nt really my issue. Its length. This started out as a 2wd cab. The PO cut along the inside of the ridge where a bolt in tunnel would go except on the back side they cut about 4" behind the seam. If I slide my tunnel all the way up to the firewall the T-case shifter is too far back in the hole and there would be no way I could pull it into 4 hi. This thing is a mutant and has had a lot of hands in it over the years it seems. I will try to get some pics up to better display it.
