I have not made any diff cover for the front diff. I have never felt the need for a front diff cover. But if you need one, I can make one.
I have actually already done some 3D-models of it (for fun).
The diff cover should fit both 36 and 37t pulley. Donīt see any problem with that, but I have only tested with the 37t pulley.
Price is $45 plus shipping $10. Know it is a bit expensive, but I have not been able to get a better price yet.
On the other hand it will save a lot of maintenance and pulleys/drive belts.
As you know this diff cover set contains 3 pieces, so it cost a bit more to make them.
