yar idea is great, but i think its not diffcult to do if you cut mehran from centre i mean between the front and back seats leg space and weld pieces all the way around. also no need to mould pieces, just take a scrap door from bilal gunj and cut it into two halves height wise. now these two halves will be suffint for both sides. roof can be simply made. the only issue is strenthening the car from floor, its required some good engineering skills
lol mehreen is best name for it
sorry dont mind spelling mistakes if any i type very fast and dont care too much
