I need a R150F not a R151F, there's no point in buying a R151F because they're the same damn tranny, and the R151F's are so much more expensive because they bolt up to 22r's. sadly enough i actually need a r150F to bolt up to a 3.slow 6 cylinder. you may ask why i need it to bolt up to a V6 and especially since i have a 22r. but i have future plans for a sicc rig. it may be a V6 but it's like my dream 4x4.
