Not to hijack the thread but.. how would I select the proper Morryde shackle kit with wet bolts? They seem to have about six different models... it looks like some are for rigs with Correct Track (whatever that is, I notice it's also the title of this thread but not otherwise explained) and some aren't. There are clearly some for fivers, but still multiple choices for TTs. I tried eTrailer's "match it to my year and model" but it didn't seem to remove any from the list, much less narrow it down to one. How do I select the proper kit for my 2019 Cougar 26RBSWE?
