If the replacement levers are the origional type of levers, it is a fair job to replace them. Replacing mine in my 230SL required removing the glove box, clock, blower control, radio dash pannel, and the radio speaker grill. With all of that off, it is posible to replace and adjust the levers but it is still not a quick or easy task.

Next question is why the levers were broken? The heater valve is probably frozen ... another interesting task and the other cables may need lubricating.

This is a job that takes time but is posible.
