i'm thinking about putting a torque plate on my 1994 dodge 2500 and i dont know which one to get. the bullydog torque plates have stages 1-4 and theres some others that say #0 to #11..i even saw a #100. but the numbered ones are a whole lot cheaper than the bullydog ones. the bullydog ones are like 200 to 300 bucks a piece and the numbered ones are like 20 dollars. whats the difference and which one should i buy? i want one of the best ones out there. thanks.
