Quarter Panel Reference

I'm in proce of restoring car where quarter panels need be but and new one put due to rust and generally how much they are bit up.

I manage get some great deal on pre 74 quarter panel ( Part Number 91150306203 GRV ) which is for LWB up to 73.

Car which i'm rebuilding is actually 75 G modell hence question will be there any issue with the fit and how different is the actual quarter panel for G model from 75 (Part Number 91150306204 )

Yes they are different part numbers but generally i don't see any major difference on the pictures and of course dimension is not given... don't want have mix up panels for each side if they are different not saying that i don't know how well will this 73LWB panel fit my G -model.

New fenders matching RS will be added however i want ensure that everything else is having right fit.
