According to the vintage Trek site, the 1983 came stock with 27 inch wheels, while the 1982 came with 700C's. Seems weird to me, but thats what the site shows. 1984 has 27 inch wheels too. Ditto 1985. 1986 was back to 700c. Maybe they got a deal on some 27 inch rims???
I would check the geometry on the vintage Trek website.
As far as the pedals, you could look into the extenders, so called knee savers. A guy sells them for a reasonable price on ebay ($19.99). I bought a set from him, they have worked well.
