All that counts is the sleeve length.The sleeve is what separates the top and bottom bushing pairs. Like I said, I used a Chevy Chevelle end link set from a 60's car on a 1998 Nissan Frontier pickup with no issues.
BTW, I am also self-taught as no one in my family and none of my friends had any real aptitude for this stuff. You learn by doing, and this is not hard to tackle. Heck, I tried to rebuild a automatic transmission at 17 years old in the garage of my parent's brand new house-- needless to say they were not happy with me after that!
