Shockers

Going to order the spring kit and associated bits for my conversion tomorrow. Going to do the shocks while I'm in there. Can anyone here advise me: can I just use the same spec of shocks as a standard EAS vehicle. The kit description doesn't say anything, and none of the P38 shocks I've looked at say anything about springs.

Anyone recommend any other bits I should do at the same time? Considering a polybush while the bits are off...

Thanks
Jock
