KA to SR power steering question

So I've done the research and know KA and SR PSP are interchangeable but I want to be reassured of a few things before wasting time and money. Here's my scenario. S14 SR with factory PSP which is obviously leaking. I've read up that S13 SR PSP can be swapped out for KA24DE pumps as long as you re-use the SR PSP bracket and swap out PS pulleys as the belts are different. Is this also true for S14 SR's? Secondly it may just be the gaskets going out on my PSP are the KA24DE PSP gaskets the same as an S14 SR? With the weather finally warming up and car season approaching here in Ohio I would like to get my pump issue resolved fairly soon. Any advice/info would be greatly appreciated. Sorry if this topic has already been discussed but I've only found information for S13 SR PSP's being swapped for KA pumps.

try taking it to a shop and get it rebuild. i have taken my sr s13 psp to a shop and they told me all the gasket and seal are the same from the ka. its been 6 years ago i remember paying 80 dollar. i have also taken a s14 psp and use it on a s13 sr and it fit but the pulley were only 3 rib and the s13 sr has 4 rib so i just use the s14 sr belt.

PS Pump on the KA24DE & SR20DET - S13 or S14, not sure on the S15. Are the same.

Only difference is the Bracket & Pulley.

S13 SR20 = 3 Rib PS Belt.
S14 SR20 = 4 Rib PS Belt because the Crank Pulley has an extra rib for the BS belt.

My S13 SR20 for example, has a KA24DE Pump with SR Bracket & Pulley.
