Undertray

Should my TR7 have an 'undertray' stretching from the front valance back to the crossmember supporting the radiator? And equally - should the radiator have any form of mesh grille to protect it?

No to both if mine is anything to go by. Don't think I have ever seen either on a TR7. I think plastic undertrays came into production cars more in the late '80s.

As far as I am aware the answer is No and No. The radiator was / is supported by a cross member at the base and is attached by brackets to the front panel. Tbh the route for any debris from the road to the radiator grille is so deviant I can't see much need for a grille. Modern cars do tend to be more enclosed. supercass

Thanks both! Working down there yesterday (at the horns) it just all looked so vulnerable to debris thrown up from the road - and there are holes which look like they could have been for fixing screws.

All production DHC's were common underbody cars so have the holes and captive nuts for the TR8 radiator's lower mount which is further forward than the 7. The 8's radiator is more exposed to road debris than the 7 as it's much lower and closer to the spoiler.

You'll also have exhaust hangers down both sides for the dual exhaust pipes of the 8. This makes the V8 conversion relatively easy for the home mechanic.....

Thanks both. Now that I've noticed this - I worry about every bit of debris on the road... I may just make up an undetray and a mesh screen. Even my Morris Traveller has the radiator protected by a grille and underpanel.....
