Fender Question

[klkinc123]

 Hi all;
My 88 90Q is in need of a new front fender.
I have looked around at alot of After market co's(Veng, ect) and can only 
seem to find fenders for the B4.
My question is; Will a B4 work (IE fit)?
Are the B3 and B4 the same?
If they are diffent what are the differences?
If it is small like a side market light I can always Mud it over.
But my main concern will it fit.
Thanks all
Kevin
