Merc top pinned ring questions??

[Vinnie]

A couple of questions for you. Do any of you gents have the part number for Merc top pinned rings for a 280?

What are your opinions on using side pinned rings cut by Mr Marles to fit top pinned pistons?

Thanks guys

Thousands in use , should be fine . Merc rings are stupidly expensive .
