Hello all, long time lurker and I think this might be my first post here...

I am expecting my first child in May and since I was brought home from hospital in my Dads 4/4 many years ago, I thought it would be great to do the same for my child in the same car. The car has been owned from new since 1973 and I suggested in passing that it would be great to borrow the car and continue the tradition, which he is all for. Due to the low line 2 seater windscreen which is currently on the car, we will have to put the high line, original one back on in order to fit the hood but that's a simple task. I just hope the hood is in good condition as he hasn't used it for many, many years!
What I am wanting to know is, what modifications, if any would I need to make to the seatbelt in order to accommodate a modern child seat?
The car has fixed 3 point belts in the front which are adjustable but not retracting. When the car was rebuilt in the mid 80's, lap belts were fitted for my sister and I in the rear but times have changed and I would imagine the best place to be will be in the front in any case?

Would I need a special car seat, if so which one as most these days seem to be isofix. I feel I can't have this conversation in the likes of mother are!

I will have to dust off my old 1980's Morgan pedal car for junior too...!😃
