Thought I would share this repair discovery with you.
Having recently bought a 73 CR home market TR6 project that only required cosmetic attention I have been looking at what I feel is actually needed to put the car in a good roadworthy condition.
It appeared that the chassis had never been parted from the tub so I decided to remove all the chassis mountings to re align the panels etc, having gone so far it would have been foolhardy not to part the tub and give the chassis a thorough inspection paint and clean.
It was then I discovered the replacement of the trailing arm sections of the chassis which had obviously been replaced with the body and chassis intact, in my view this is not a practice to be encouraged, the chassis section was only welded in place bottoms and sides, no attachment to the top rail of the chassis at all, the top T shirt plate had no structural duty at all having been cut to remove the old chassis members. Have now replaced the top T shirt plate and welded all tops of the trailing arm chassis, hopefully the chassis has not lost a great deal of its original shape.
Not having driven the car the way it was I cannot comment on the effect this repair may of had on the handling but can only assume how much flexibility the chassis would have had without a top T shirt plate functioning.
This type of repair to the trailing arm chassis has been regarded as a cheap quick fix repair but surely not one I would advise.
