Patio door roller replacement

Question

Your 81-148 Roller Assembly looks to be a perfect match for what I removed from my 35 year old doors. Unfortunately the 3rd tit is located about 3/8" too low. I ultimately decided to rebuild the old assemblies and just replaced the rollers. However I have 3 more identical doors and wondered if you have the rollers with the 3rd tit closer to the vertical center.

I'm not sure if that will matter. The bumps on the sides of the roller are just there to thicken up the housing. They do not actually have anything to do with installation or the operation of the roller.
