300te self-leveling delete

[kjcst20]

the right rear shock on my 1988 300te wagon (137k miles, 2wd) has sprung a leak. i havent had a chance to determine exactly where the leak originated, but in less than a day it has emptied the entire hydraulic fluid reservoir on the ground. i'm assuming it is the accumulator as it looked like it was dripping from the top.

i want to know if anyone has done a self-leveling delete, or if this is even possible. as nice as the system coud potentially be, i'm interested in simply installing a pair of biltein HD's in the rear. does anyone know if this would cause any handling problems? also, can i use the stock springs?

if this would cause more trouble than it's worth, are the accumulators hard to replace, or should i have a shop do it. i'm an average diy'er.

thanks.
