wrong rear propshaft fitted, any damage done?

so the previous owner of my 90 had it for just 5 months and with respect, he didn't have a clue!
The only thing he mentioned that he change was the rear propshaft, i should have known to check it before now.

Anyway i went to remove if for the first time today and had to jack the chassis very high before it came out as its too long and its completely compressed between the diff and transferr box with the propshaft travel seal pushed right up against the front UJ.

The propshaft fitted was part number FRC8393 which i believe fits 300tdi and td5, but i need FRC8392 for my 1994 200tdi 90.

Im obviously going to order and fit the right prop straight away

QUESTION IS.. will it have damaged anything as I've been using if for the last 3 years! is there anything i should check? and will it have been reducing axle movement?

Cheers all.

if its been running like that for 3 years you might be lucky, it will have put excess pressure on diff bearings and t/box rear output bearing, but if truck seems to drive ok just fit correct prop

It will have been limiting movement some and I would have thought if doing any serious off road stuff you would have felt it bottoming out at times. Still as James says you might be lucky.

yeah the trans box and diff bearings both seem nice and tight with no play at a glance, I'm having both the diff and the rear output shaft off this week to change the seals so ill have a good look.
And Tottot' i have noticed a very harsh thud at times when off road, this may explain it!

hopefully no serious damage done though
