R134A A/C Conversion O-Ring Sizes

[Inniswhe]

I am painting my 84 Carrera and thought I would replaice my A/C lines with barrier lines while I have the fenders off.

The connections on my 84 (constructed late 83) A/C system appear to be the O-ring style .

I am going to purchase the Rennair Hose kit and am wondering what size/quantity of O-rings I will need.

A/C has not operated since I purchased my car a couple of years ( seller claimed it needed a recharge) ago but I am planning on upgrading to R134A and getting the system opoerational later in the year after the painting is complete

Does anyone know o-ring sizes / and quantities ?

Thanks
