p audio pa d25 diaphragm [or similar that will fit

HELLO! long time no post
My friend/neighbour/landlord has asked me to help fix an old peavey pro15 that appears to have a dead compression driver, Im going to be looking at it later to test it isnt the crossover or a loose connection or whatever
from the pics he sent me im almost certain its an 8 ohm pa d25 [and believe me ive seen alot of those drivers back in the day lol the code on the back is the same code as well lol]
problem is its likely its either the crossover or the diaphragm [not many other options lol] 
the diaphragm appears to be out of stock/production in most places 
any one have any idea where to get a diaphragm for one of these nowadays? blue aran has it listed as discontinued il probably email them just to check they dont have an odd one lying about old stock but thats a long shot lol
so if anyone knows where I might be able to find one he would be most apreciative
if not i guess il have to just swap the compression driver out for something else similar which isnt an issue id just rather fix than replace though old fashioned i know
hope everyone is enjoying the weather and thanks in advance for any replies whether they be usefull or just funny all good lol

my memory is awful but i think its the same as the jbl2412 from memory 
since i gave up drinking my memory seems to be a bit hazy lol but i am very backwards
im going next door shortly il measure it and compare it might actually answer my own question for once unlikely im usualy pretty useless but even a broken clock is right 2 times a day if i do then thats 2 times in one year for me which is record setting LOL!
il look into the ohm rw3 hf see if that lead helps much apreciated

so just been next door
its not the diaphragm its a fuse on the xover lol so yeah game on
and yes it looks like they are available so il get him to buy one just incase so next time . lol
much appreciated for the help :-) i know for when he inevitibly breaks it again lol
