Thanks guys. Ill be picking up the sm420 this Thursday. I may also be getting a sm456 that already has a adapter on it for toy cases.( pending) anyone know if the 456 will bolt right up to my 4.3 like the 420 will? I know the 420 has a lower first gear, but the 465 has the adapter already on it( will save about $350) I will go with the 420 is the adapter on the 465 will fit the 420. anyone know? Also i will be doing a build on this one. To bad the only toyota part will be the duels. I'm building a s10 blazer with d60 and 14bolt on 4dees. I'm going with the s10 blazer for the fact that its just like a 4runner and already has the 4.3 in it. plus it has r12 a/c oh so cold.
