Re: How do you tell T18 from T18A?
first of all $1600 is higher than astronout ganja! for a rusted out Jtruck.
second the transfercase adapter is NOT what makes the T18 longer from a J truck, if the J truck hjas a V8 then there is a spacer between teh bellhousing, and tranny, and a VERY long trans input shaft, it can be swapped with a FORD input shaft to ge teh short T18, like used in CJs
BUT its got a 1" adapter to a Dana20, you not saving ANY money going this route if your planning to use it in front of a dana300.
there were some T18a used in 81-83 J20s that will bolt to a dana 300, but they do have a 5 inch or so adapter between the trans and teh Newprocess Tcases they came with.
My T18a came from a 79J10 with a 360, its granny.
too small to be seen, and too big to control, and treated like a walking bomb...
