Does PL411 use same ball joints as Roadster?

["Pete Peters" <ppeters914@comcast.net>]

I haven't inspected the ball joints on either car, but the visible grease is
caked and the boots are dry and cracked, so odds are good they may need
replacing after 40 years.

Anyone know if the PL411 and Roadster use the same ball joints?

Thanks.
