well you have the FB 79-85, then you have the FC 86-91, then the FD 93-95
I would say that the weight of the FB could rang from 2300-2700 depending on year and options. my 79 thats striped most likely weight is about 2100-2200.
Most FC weigh about the same through all the modle years, so that would mean 2625lbs to 2850lbs depending on model and options.
