powertrax lock right

[exb5182]

Just a quick question I've searched throught the forums a bit and haven't really seen this question addressed. I have an 8.6 open carrier rear out of a 08 trailblazer. I've been looking at powertrax lock-right lockers and even on their pfd application brochure they dont list a lock right for an 8.6 30 spline diff. Could I use the 1921-LR which is for a 30 spline 8.5? I may be completely wrong but isnt the only difference between the 8.5 and the 8.6, the carrier bearing? So as long as I am using a lunch box locker to fit in my open carrier and it is an 8.5, 30 spline model it will work correct?

I believe that is the correct lock right for the 8.6
