'92 Park Ave to LeSabre Power Antenna Swap
 

Today I installed the power antenna from a '92 Park Ave into my '92 LeSabre.
Yes, they're different power antenna units, but it was pretty much a bolt-in swap -
I had to use the exterior grommet & chrome retainer from the Park Ave's antenna,
and install the shorter support bracket from my LeSabre's old antenna unit onto the Park Ave's unit.
Other than that, it's a simple & inexpensive bolt-in replacement/repair
if you happen to have a LeSabre with a broken power antenna but only Park Aves in the local salvage yard..

Thanks for posting the info!
