HELP Decided on these shocks, will they be ok ?

[aussie87]

I have decided to go with these shocks for my 1987 Stepside.
Front KYB 565032 Monomax
Rear KYB 565036 Monomax

As I am buying these to be sent to Australia, are they the correct ones for my 87 ? Want to make sure as a bit hard to send back. best buy I can find with freight is from Rockauto online shop (US$) 315.00

Here are a couple of side photos, how much do you think it has been lowered from factory ?

And will standard shocks be ok to fit or will I need different shocks ?

From the ground to the lip of the FRONT guard it is 2 feet 4 inches

From the ground to the lip of the REAR guard it is 2 feet 3.5 inches

Any feed back is greatly appreciated
