Exact measurements, rear engine, rear wheel drive

It is very hard to find a base car that meets all necessary features to make a perfect replica at an economical price. Please do not trust ads which offer exact features of the original at cheap prices: it might likely be a picture of the original car and, at best, pictures or videos taken from other builds/manufacturers. Could be the man/hour price will be cheap in other countries, but, engines, wheels, brakes, etc, cost nearly the same in all countries.
