1982 mounts
Hi all,
I am not sure which mount need to be replaced, but when I shift for P to D mode it feel like the car "become lower" or drop down.
I don't have vibrations, noise or anything like that but I hate this drop each time.

Perhaps join a Corvette club. Have a experienced member go for a ride with you.
your description leaves a bit to be desired.

I would agree you need to check the pinion snubber bushing. My '80 needed that. I also had a cracked leaf in my rear spring. You might not need to worry about that if you have the fiberglass monoleaf spring.

I was going over some old post after your feedback and it sounds like its describe my problem.
I also read that the 80-82 are different and much harder to replace than 79- . One person said it took him almost 6 hours to complete the work.
Does anyone recently done his Differential snubber bushing?

A thump is a snubber bushing, and should be repaired. You might have to pull the driveshaft or differential to do this. It's on my list when I swap the transmission.
Otherwise, the squat is normal. You can play around with the idle speed, and I think there is a vacuum modulator issue that exacerbates this.

Some pull down is normal, you need to check the snubber and determine if its worn. Your car is over 40 yrs old, if the snubber has never been changed and you have a lot of miles on the car, I would change it.
