Nomondo!!
The catchers won't fit. I'm "gaina" try and get the motor on the Vantage (just visible in front of it) going with any parts of the Rover, and then transfer that onto another Victor chassis. Plans don't always go to plan.
I may just strip for bits.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
