I have a 78 Holiday 88 with a moonroof. The glass is 22"×37". Did they have different sizes. Went to the salvage yard and I seen 2 other sizes (looked the same as mine but the size). Also anyone know where someone can get replacement glass and probably hardware by the time I'm done. Thank you in advance for Any help I can get for this restoration

 

It would seem unlikely that they would have different sizes, at least in the same model year. Those other ones you saw in the salvage yard, were they also 1978 Delta 88's?

I would guess replacement glass and associated hardware will have to come from a salvage car when you do find one. Certainly none of this is made new now.

I have a '78 Toronado with a moonroof, and while the glass and hardware are OK, I needed new weatherstripping, which is also not availalbe new. I ended up finding something aftermarket of about the same shape and gluing it in. You have to get creative sometimes.

 

The one I measured at the salvage yard were different cars. One was a Grand Prix and the other was not an 88. The years of these were the same era (77-79).
Not sure what I'll be getting into it to see what else I can damage. I just have to take it slow and not break anything. That's what I'm up against on this restoration. I have the front and back off. Seats removed and all I've had for messed up screws or bolt were 3 on inter front fenders that I had to cut off. Luckily they were ones that went to a clip. Hope I don't break any off when I take the body bushing bolts out.
Thanks for a little insight on this. Much appreciated

 

Maybe it's aftermarket. There were plenty of aftermarket T top manufacturers back then. Pictures definitely help.

 

Is this a factory astroroof that retracts into the car's roof, or one of the pop-up aftermarket pieces?

Pictures please to help us identify it.

 

I've never had to open. It does have a crank in the front middle of headliner. Here are some pics

 

'78 Delta silver tinted astroroof glass was part #20148490. '78 Grand Prix silver tinted astroglass was part #20148484. Something is different - I would imagine the Grand Prix is smaller.

 

Mine has the silver tint

 

That appears to be a factory moonroof.

 

That's kind of what I was thinking.
Make me wonder how many 78 Holiday 88's with a moonroof and a 403ci were made. Not sure all the options they had that year but haven't heard of any that it doesn't have
