When you look at the gland nuts that came with the inserts, and slide one down over the
spear, you will see how the nut sits on the top of the cartridge. How much thread engages
is governed by the how far the top of the cartridge sticks out of the strut tube and how far
the nut will thread in (assuming you have the correct thread and the nut slips down over
the top of the cartridge until the nut is in contact with the clamping surface).
Then look at the OEM gland nut and figure out if (you had the inside machined to the same
dimensions as the KYB gland nut) it would work. I'm picking that if you have more than a
couple of millimeters of the cartridge sticking out above the top of the strut tube, then
you are screwed

possible, you will still need to find someone with a lathe who can open up the OEM gland
nuts for you.
I see that T3 do some kind of "universal" gland nut to suit the AE86 strut tubes for $45 a
pair. Might be an alternative. Sell the rears to someone who is running stock length strut
tubes and wants to fit stiff springs (so needing short stroke inserts) or offer them up on
a MR2 site. Sometimes better to cut your losses and move on...
