A question about the 164 R ballpoint

[Chandon]

Does anyone use a burgundy Montblanc 144 ballpoint or rollerball? I like the colour more than the black versions and was thinking about buying a pencil and ballpoint to match my early 1990s burgundy fountain pen (which is still going strong nearly 30 years on). As an aside, I like the old Montblanc pen sets from the 1970s and prior years and wish the company still made something similar today, such as a Classique fountain pen and pencil combo.  Am I right in thinking that the 164R ballpoint will take the modern Montblanc ballpoint refills. Any help or thoughts would be most appreciated. Thanks in advance.

The modern ballpoint refill should fit all of their ballpoints

Thanks very much for your help. I asked the question because the length of the refills changed back in the 1980s or 1990s. I have to use my 1970s and 1980s slimline ballpoints with a modern refill with a spacer added on.
