[TR] TR4 rear dampers

[Dave Hogye]

Peter will share great recommendations.  
I think the valve can be adjusted too. Although I have not done this.
The leaf spring band bends need to heated red hot with a torch before spreading them or they will break. I have done this.

Referring to Barney Gaylord’s page https://mgaguru.com/mgtech/suspensn/fs110.htm  the standard weight oil is about 20W or ISO 68 (Peter Caldwell World Wide Imports). Hydraulic jack oil ISO 32 is 10W and fully compatible. I will call World Wide tomorrow for clarification. Has anyone tried this?
