later interior with 3 proper seat belts.
 

I have an R reg classic, can I swap the interior for a later one that has 3 proper seat belts rather than the lap strap, I have 3 kids and on the odd occasion I need to use the scooby I want them to be safe.

What year did they start doing the 3 seat belts on the rear?

And will everything fit or do I need to alter seat mounting points?

anyone?
