This one,(and the berg) are very good, but not billet like the LanD.
The one on the link is for 113 bearing.
You can possibly order it in advance with 002? or
machine the housing for the larger bearing when you get it or
machine the mainshaft down to suit the 113 bearing.
I have done variations of all these things to get parts to fit.
Bergs used to come with either 113 or 002 but not 091.
That may have changed.
They are from here and I just phoned and using my Visa, it was sent in the post.
LanD will only use PlayPal which I found to be a PITA unless you use that stuff for EbAY.
I know I can't take the money with me, but wow! Are the Berg's offering a bar of gold with that housing❓🤪
By the time you buy this housing, box, upgraded parts (albins gears etc) and get the box built your better off getting a G50 Porsche box personally
Appreciate your input
