Need to order carpet, all the catalogs say floor shift manual trans and 4x4 are big hump and 2wd auto are small hump. However I have heard all bolt in humps are big....Im confused because I clearly have a bolt in hump and cutout for standard trans if needed.
1976 GMC Sierra C15 2wd TH350 trans with 350 VIN L engine
Is there another way to tell?
Heres a view looking from underneath my truck
