replacing tonearm question?

Hey,
I have a VPI HW-19 MK4 which I love dearly. My existing Sumiko FT-3 tonearm is 20 years old and on its last legs and I want to replace it with a Jelco 750 or 850. Both arms are 9". Would I have to have a new armboard made and drill new holes? Or could I use the existing armboard and hole and just drill new screws? I know I'd havr to factor in the tonearm radius and all the millimeter differences.

I've never done this before so please excuse my ignorance on this.

The pivot to spindle distance of Sumiko FT-3 is 221.7mm, and the Jelco 750 and 850 is 240mm. I think a new armboard is required unless you use a tonearm with same geometry (e.g. clearaudio) than you can use the existing armboard with some work.

the 9 inch Jelcos, which use a Linn mount and have a 214 pivot to spindle
@hdm , thanks for the clarification, 240mm pivot to spindle is for 10" jelcos!
