Smile XP to XR 3speed gearbox upgrade mods needed

Hi
I have an XP with a leaking 3speed gearbox and finding it hard to get it in gear.
Thinking of putting an XR 3 speed synchro in.
Does anyone know what has to be modified for it to work?
Is it worthwhile?
Thanks Heaps
Darryl

It’s the “large back” type block, like an XR?

I’m not really sure.
It’s an original 170 pursuit.
It has an original 3 speed non synchro gearbox. 4 bolt holes on the top of the gearbox.
Someone told me that it’s best to put a later model gearbox out of an XR falcon.
It’s a much stronger box with synchro in first gear.
Just wondering what modifications I need to make it work for me?
Cheers Darryl

That might be the small bellhousing type block unless it’s a very late XP, if so you’ll not find it straightforward to put the later box in. Having the selector shafts and their bushings rehabilitated could be an easier choice.
