KVA build instructions

Does somebody have build instructions for a KVA.
Chassis in not the problem, its all the other stuff that needs to fitted to the chassis.
I bought a stranded project. A rolling KVA chassis with body & ancileries fully dismantled
Need guidelines as I want to do it correct.

Body is a MK2 & thats why its dismantled. Somebody started the conversion. Its me to finish my dream.

Any help apreciated.
