Shock extenders for Bilstein 5100s

Does anyone know if they make shock extenders for the rear Bilstein 5100s?
I just got the rear TSB done and it sounds like my rear driver side 5100 is topping out when the suspension is being cycled. I just bought these rear 5100s so I dont want to spend the cash on some 5150s or any other longer shock at the moment. So thats why I want some shock extenders to help fix my problem.

I know Toytec offers the shock extenders for the stock rear TRD Bilstein shocks but it doesnt look like it will work with the 5100s. I know the stud size and thread pitch is m10x1.5 on the rear 5100s only because one of the shocks didnt come with hardware. So I had to pick up a nut for the 5100 because the stock TRD bilstein nut was a different size. I've found shock extenders at Autozone but they only have them in 3/8-24. Anyone else know of where I can find shock extenders that fit the m10x1.5 stud

 

I need some extenders too...... mine do the same thing and I'm in the same boat as you.

 

Anyone ever try these. I found out they do make them for 5100s. Just get the 1.5
