I think the thought that will have gone into this box etc will have been extraordinary. BUT IMO there is nothing you can do to a bc or ib5 box that will make it stronger than an mtx75....

Im sorry, but why didn't this company spend more time pursuing an mt75 conversion kit, ie off the shelf brakets/mounts etc to create an easy conversion.... 2.5K is well out of many peoples reach, any one proper with that amount of money to spend will pay some one else to fit an mtx75 with a Quaiffe atb etc and still have a cheaper and i suspect better solution.

Your 6 speed will inherently be weaker than the 5 speed too, so although i feel guilty for putting down what im sure is A LOT of hard work this just isn't a realistic solution to the weak gearbox in a 20+ year old car.
