I just got my 1996 Riviera with L67. I believe the motor mount and trans mounts are slightly worn even with 82k miles... However, AC Delco doesn't even make the mounts anymore. So right now there are only the DEA/Westar/Anchor mounts from Rockauto. Do these mounts last? I've heard some bad stories about them. Or is there any place I can get Delco trans mounts for the car?
My current solution: Use Delco mounts for 96-99 sc Bonnevilles, use the insert and put into the old bracket.
Trans mount: Use the aftermarket ones?
