There's a guide here
http://www.pbresource.com/legs.html
For correct leg sizes !
Well there you go learn something new every day, my T2 has 31" legs, F14 has 28 1/2 " and FP has 27" going by that guide they should all have 28 1/2" only measured the front ones assuming they should be the same at the back.
Looks like" I need legs you know where to get them" kind of reminds me of a ZZtop song
