I reached out to Bilstein US for any further insight on our shock situation, but also specifically for a two inch lift. They responded with..
"Thank you for contacting us about our products. As you know we do not build specific shocks to fit a lifted Delica but we do manufacture a line of B8 5125 universal shocks. These are primarily fit by extended and collapsed lengths and come in “stem to eye” and “eye to eye” configurations. I have attached our 5125 fitment chart below for your review. As for the valving, we only have the one shock for the front that will meet your length requirements. On the rear you will want to go with our 255/70 valving for your Delica. The 170/60 will be too light.
Please keep in mind that these shocks are universal and some modifications to the mounts may be necessary for proper install."
I attached the chart they sent me if it could be helpful for anyone else out there. I'm gonna try it out and see what happens, since Bilstein seems ok with doing some modifications for the fit. I'll be putting the 33-230405 on the front that fits. And then trying to use an adaptor for the rear eye-eye 33-185590. There will be a delay in the results, I'm waiting on an engine from Karr Auto and will be having them do all my work so once it's done I can give ya some feed back.
