Recommendations for V3 tech?

[Randymanpipe]

Hi all, 

I’m looking to have a new good spec V3 gearbox built and fitted into my RPK for the 2025 season. 
Can anyone recommend a tech that would be able to help with this? 
 

Am happy to ship it so not location limited. (Uk mainland only) 

thanks in advance,
