Chassis options for a scaley TR7 refurb.

1. JS chassis (pic above) 
https://slotracer.online/community/showt...hp?tid=784
Not really suitable for my needs. 
I prefer chassis' with floated motor pods and suspension 
I'm also looking for  long can inline motor support.
The weight of the long can would help to stabilise this short wheelbase, short guidebase car.

2. Shapeways chassis pictured below.
Long can inline is possible with a Slot.IT motor mount.
Expensive. The black premium version would be a "must" for this refurb because so much of the chassis is visible at the sides and rear of the car. 
White would just not look right. Shipping cost is a killer. The April free shipping offer would not have helped because of the £99 minimum to qualify.
I like to spend time on my hobby not throw too much beer money at it.

       

3. chop the existing chassis and put a pod in to it? (The GeeMax solution) 
Too old, too "shapey" too fragile (the front of the chassis has already broken off and been lost) 

4. find an existing flat chassis from a modern car and cut to fit. 
The rear detail would be cut from the old scaley chassis and attached to the body, a technique used in DiSCA racing for diffuser detail.
The short wheelbase (approx 74mm)  and guidebase (80mm) are untypical of modern cars.  
The  nearest i can find in my race box is the Racer Sideways Lancia Stratos but it's not a perfect candidate.
Manufacturers don't bother to publish chassis dimensions so searching online for a suitable  chassis is not easy.

If anyone out there has a modern car with a flat chassis that  matches the dimensions , please post in the thread. 

5. Slot.IT Hod Roddicus Supersonicus. (HRS) 
A generic retrofit chassis 
I've used the HRS chassis previously (on the Proxy Megane that is currently out on tour)
The chassis does work reasonably well but  could be improved. 
One challenge with HRS2 is that the front axle to guide length is fixed. On some cars , there is not enough forward space for the guide and the spoiler detail has to be chopped away to allow space for the guide. 
A second challenge is that the body mounting is done via side cups to ensure it will fit the majority of cars. 
A generic chassis would never be able to match all of the different body post arrangements out there. 
However, for the TR7: it has no body posts so fabricating new ones to match the 2 holes on the HRS chassis should be possible.
It might even be possible to create a way to create corner stabilising set screws for this chassis body combination.


In summary  are, options 4 and 5 are the leading cases. 
1 2 and 3 i don't see as viable.

Any alternative suggestions are welcome.
