mA A sockets are ok (probably they haven't seen much use). It's the voltage one and the common who are problematic .
the 87-iv shares the same socket with 187 189 series but I can't find them for less than 40 euros around here which I consider ridiculous for such a part. So my current strategy is to turn them around and use the ma A sockets for V and common and repair the broken ones with messing pipe.
After all I didn't use the messing pipe as Mrmodemhead did (even though I took a lot of courage from his work, here
http://mrmodemhead.com/blog/fluke-80-series-jack-assembly-rebuild/#comment-231595).
I decided to use the old broken pieces and attach new leads. This was partly because in euroland we have only 4-6mm (OD) which doesn't fit our 4mm (ID) sockets.
So I took out the broken parts, (4mm-4,5mm drill in the center to take the plastic out only 5mm deep is enough). I soldered pieces of wire on them and filed down the outer part to be smooth.
Then I inserted it back in the plastic (it has a guide so it is easy if you dont drill too deep). I put a small 3d printed cylinder of 3,5mm to keep the distance (not sure if it was necessary) and then epoxied the whole thing.
As I don't know how long my handwork will last, I soldered the sockets the other way around. So the repaired sockets stand on the mA and A side, and the non broken ones on the Volt/common. Works pretty well, as now-a-days I usually use the clamp meter for the Ammeter .
PS should I change the title of the thread to reflect the repair part?
