Default ucf20/ucf10 OEM control arm question

Its understood that the ucf20 suspension is longer than the ucf10. What I am looking to do is install ucf20 suspension in a ucf10. I sold my 90 ls400 with k-sport kontrol pros c/o and the guy loves the car but hates the stiff ride. He is looking to trade out susp. Does anyone know how much higher it would it sit with ucf20 oem suspension in there? The k sports are meant for a ucf20 but they are adjustable so it fit in fine. If the ucf10 would end up being too jacked up with the ucf20 suspension, could I swap over the control arms from my 97 parts car? Thanks

control arms won't swap properly
suspension may but you'll kill the shocks and your susp. geometry will be way off. not suitable for anything more than rolling the car around the shop.

it's a difference of shock piston length, so no, changing the control arms (what would that accomplish...) won't do anything.

the ksports were designed and tested on a 1LS, so they'll fit a 2LS fine.

Would you happened to know the eye-to-pillow mount length of the 1ls and the 2ls?
