There are several good 914 books out there - each with a different focus, depending on what you're looking for as a reference (mechanical how to, authentic resto, interesting info, etc.). You'll also find some conflicts, incomplete info., & B. Johnson's is all B&W, but helpful nonetheless.
There are several to add to your collection & I've put cover pix below. It's best to Google or use one of the book price search sites to see who has the best price, & I combine the Borders online coupons to get even more off (33-40%).
