The VW cars are mostly IRS. A Miata rear should work but I have not seen one employed as such. last year I saw an actual 53 TD with a super charger and age-appropriate Triumph IRS. But I did not crawl under to inspect.
Ed, if I remember correctly, the TR4A was the first with IRS in 1964. Not quite the same era as our TD’s – but close.
Looks like you’re right, Roy.
The LaBrush TD has a Jag rear but I think that car is overkill in every dimension.Maybe the RX7 will work. Never though about a Triumph and agree Jag not a good choice but at least the Jag axles would be easy to make correct length.
I mis-remembered about the TR rear. Actually, it’s a ’50 TD with a 5 speed from an Austin Healey and MGA disc brakes.
Langan, why did you rule out the Jag? Most irs are not independant of the frame and require hinge and radius arm mounts that are critical. The jag rear is a unit that would just bolt under and includes everything including springs etc. You often see them under hot rods because they are easy to use, handle 400 hp and they also have inboard disc brakes in the unit.
