i was told by a guy who has been "in the business" for 20 years and says that conical and acorn seating is the same and that ball seats are different.

do you know what kind of seat a dsm would have (98 eclipse), i dont want my wheels to fall off

 

"Acorn" has several meanings - some use it to refer to ball-shaped seats, some to lug nuts whose outer gripping surface is round, etc. However...
