That is one nice looking B! I have a 1950 that looks identical (except no sickle mower) that needs that kind of attention ....! My steering drag link is bent like yours, only not as much - the previous owner(s) apparently used it for a step regularly, and it's not hard to bend those things. Getting it bent back, now, that's a challenge! And my front end is bent up where someone apparently liked pushing things with the front end for many years - go figure.
Here's the question - where did you buy your seat? My 1949 B came with an uncomfortable brown bench seat that sits too high - I need one like yours (my 1950 has one just like it and it sits nicely).
