Need help! Stupid build.

[connor19]

Hi all ill start straight away by saying this is dumb and a lot of you are gonna think im ridiculous but...
im wanting to start a cobra 427 hardtop build from scratch i.e building chassis and body etc, i have sufficient knowledge of using a mig welder too and i have a general idea off how to build a body using framing, foam and fibreglass.
But thats all i know, the other stupid reason to all this is because im stuck at home under quarantine and on my drive sat haunting my dreams is my old 1L automatic nissan micra, so basically what im trying to do is
1. find exact dimentions to build a chassis
2. find dimentions to make the body
3. transplant as much as i can from the donor car (trying to make this build an automatic)
4. up the engine to a 1.2, 1.4 (insurance is hell ain't it?)
5. fit the electrics in.

I know this is a lot but im on a fairly limited budget and working with what i have, i will appreciate all and any help throughout this terrible idea,Thanks!!
