Item one, learn to read.
Have you ever ran them ???? I have for years and never had a problem with my pinion angle. I can send pics if you like ... you just have to make sure they are 7-leaf waggys and not 5-leaf.
Item two- go ahead, we may just have differening opinions of what an okay pinion angle is.
