Not sure it will help but .
What number is your CAV. Mine is LH drive, #193. I will look at it and make note of L R differences if any.
If your lucky a dash and rack may be the big items.
Not an expert on this but since CAV offered LHD and RHD it should not be too difficult. Key question is, do you want to keep the gear lever in the center position or move it to the rhs sill???
