4 of 5 adequate quality October 22, 2024
Reviewer: Cookies from Crawfordville, FL United States  
no issues, the seals frames could be made a little better..not as thick or wide as oem in these kits...had to reorder flywheel side 2x because of buckling that creating a ripple during pressing.  locking sealant is a good idea
