I have a 1989 Bonneville SSE the moon roof gears are stripped and the moon roof needs to be pushed by hand otherwise it grinds and doesnt open. It was already fixed once and is now broken again. I have a 1991 Bonneville SSE that is my parts car and the moon roof works fine. I was wondering if it is a fairly complicated procedure to remove one moon roof and replace it with the other or should I let a professional do it ?

You may only have to change the motor. The gear is on it that drives the cables.
Please see my post:

Well I dont think its the motor

it grinds and its rather loud...u have to push the glass back to get it to go into the full open position. the pop up function works....the gear or what have you has been already repaired by the previous owner once...it needed something welded

The gearbox and motor are all part of a one piece assembly.
The actual roof slides on a track with cables that you could see when the roof is open.
I just replaced mine on my 90 SSE.

Well I will have to take it apart and look at it. Thanks

Might want to check Mazda'*, I understand RX-7s of the same period used the same moonroof.

Kool thanks...I dont need a new moon roof tho. I already have one that works perfectly fine in the 1991 Parts car. I am more concerned with the complexity of the swap.

So does anyone have any info on the complexity of the swap or at least how much it would cost to have it done by a pro?

any info would be much appreciated

I just want the 89 to run like a top...well the engine and tranny do and yes my compass and DIC work altho it needs a good cleaning.....it doesnt like the cold LOL

I think getting the headliner out in salvagable condition will be the hardest part.

Well if worse comes to worse...I will just have it replaced....I am contemplating having the cloth interiour changed to gray leather....dont know you....so it is not an issue
