The YR instructions are very small to read but if you take your time everything goes together perfectly. I spent some time manually rotating the front and rear Exotek alloy diffs after installation to work them in with the new grease. I used Tamiya diff grease and then built up the Exotek turnbuckles then added 4-Exotek PRO5 12MM clamping matching hexs to finish off the installation.

Someone asked what comes in the YR kit...

I posted some pics of the Exotek driveline upgrades installed in a previous post. I decided to keep the stock shocks for now until I can decide what upgraded aluminum shocks to go with on this car.
