Everyone builds them slightly different. Mine has full gussets everywhere. 3/8in and 1/2in steel throughout. Others make it with aluminum or 1/4in stuff.

template is just fit it around and weld then test fit.

Aloha all,
So I will attempt to build on myself yet share my results/ dimensions to help others hopefully. These are my results your may be slightly different, use this as reference only.
NO measurements will be in pictures till the final fit to ensure erroneous info is not out there.

need4speed069 built a few somewhat recently, you might reach out to him and see if he's still making them.

this is what real hot rodding is all about, making your own adapters to put two pieces together that were never intended to go together; good luck
