Atta boy. I got some from my local HOLT of California store awhile back. If I can remember where by toolbar parts books are, I can try and look up the numbers for you.
Not sure if anything is in the members only section yet. If not, I should share for the benefit of others. JM
Here is what my D4 tb book shows for the cylinders 1- 5k7054 seal, 1- k 7110 packing, 1-2h3917 seal, 1-1 h8128 seal per cylinder
I redid my tool bar cylinders a few years ago and I found everything I needed at a local hydraulic shop.
