Does anyone have Mac#1 chassis dimensions?

I'm looking to buy an exhaust system which was intended for a Mac#1. But I will be using it on a Haynes Roadster.

I want to try and work out how close the Mac#1 chassis size is to the Haynes - so does anyone have chassis measurements for the Mac#1 that they can share?

Do you know which mac1?

They could all be the same,but they did different named ones.

I've got a ZR I could measure if you get stuck.

I'm afraid I don't know anymore detail. The main measurements i'm thinking about are the width at the point where the engine bay starts, the same at the nose, the total length of the engine bay, and the depth from the top chassis rails to the bottom chassis rails..

The original chassis the exhaust was build on was a MAC#1 ZR with a 2.0 Pinto.

I cannot remember are the ports slightly different between the 2.0 and 1.6?

I'm hoping not on the basis that there are lots of pinto exhaust manifolds on eBay listed as suiting "1.6/1.8/2.0" - i.e. they are all the same....

Here is the exhaust in question on the car it was built on:

If i remember right the mac and the mk indy was the same so if any one has a indy with a mac exhaust it should fit
