If you have the ability to do the widening of the front and rear guards like say an old Audi Quattro I think it would look fantastic, the wide edge right down the side at top of the door height really lends itself to this.

I have often thought about it but its beyond my metal working capabilities.

Those brakes are probably overkill,I have always gone the smaller lighter faster route, but if its getting a CA18 transplant it should have plenty of power to spare for whatever weight you care to add.

Its everyones dream to build the ultimate Datsun, I say go get em ,I cant wait to see it.
