Editing RB25 Gearbox - Installation (section)

==Tailshaft==
You just have to get the front yoke on your tailshaft changed to suit the RB25 box. You can get these brand new from Hardy Spicer. Any tailshaft shop should be able to get them. Local and import cars run different sized universal joints so you will need the correct yoke to suit. Imports typically use 27.4mm universal joints, whereas local models typically use 25mm universal joints. Be sure to measure first as this can vary.

* Yoke to suit 25mm uni: 2R-3-2938
