You don't need fabrication skills to build an ERA. It is not like some of the less expensive kits where you have to weld, fabricate, and re-engineer the whole car while building it.
If you can pull an engine out of a vehicle, rebuild it, put it back in, and get it to run, you can build an ERA. The kit is very well designed, and the only things that won't fit like they're supposed to will be things you thought you'd "improve" by modifying them
