Odd 1970s door sizes

[andybigbassdrum]

I'm hoping to replace all my existing 1970s internal doors. The problem is that these are all approx. 1960mm tall. I've looked at dozens of 1981mm tall doors for sale, but none of them allow you to trim more than 12mm max in total (I need to trim about 21mm).

Anyone know where I can get doors that can be trimmed up to about 25mm?

I've trimmed a couple down before. Planed until the bottom wood section was gone, then inserted a new one with wood glue and clamps. Once it was dried, planed again until it was the right size. Didn't take too long....
