Surrey top conversion TR4A


Recommended Posts

One small point that hasn't been mentioned about the original "tuck in" front fixing arrangement is that it is much easier to store the surrey fabric in the boot, useful when boot and rear bench space may be at a premium on long tours.

Incidentally wind noise can be greatly reduced by feeding a length of small section glazing gasket under the lip, removing in seconds when you need to do the tuck.

Horses for courses! The Surrey top fits very neatly in the back of the boot.  Rolled up It doesn't take up much more room than the frame anyway and does feel very secure when fitted. As  I do not intend to do any long tours with my car it's fine for me.

However with this upgrade by using the original  4A  soft top parts, windscreen, capping and rail, for any future owner if stowage is a concern, then a replacement Surrey top windscreen capping and a standard Surrey top would return it to original style  fitting

Cheers

I seem to remember someone used a couple of straps fixed to the inside of the bootlid frame to take a rolled up Surrey with frame inside.

So after much research and looking at the various approaches taken, I opted for the Revington modification to the TR4a windscreen frame to provide indented locking cams for a Spitfire soft-top frame bar. The Moss 4a Surrey frame was modified with the fwd tubes being shortened and then tapped to M10 both ends (pinched from Damson6 - thank you!), a length of 10mm studding connects the 2 parts. I had to the change the angle of the flattened ends of the frame legs slightly and also flattened the outer 'ear' of the Spitfire header rail to give a better location for the pins on the end of the Surrey frame legs. I also used the hard rubber bushes from the 4a arrangement to fit to the pins and locate in the header rail ears. The added benefit is that I now have adjustment at the front and back of the frame :)

I think you may find you`ll struggle to engage the header rail with the frame with that sort of fixing at the front once you have the fabric attached to the header rail, the idea of the "Z" engagement with the Revington frame is so you just turn the header down around and engage with the frame which is already adjusted to suit otherwise there will be a lot of faffing about which isnt good when its come into rain heavily.

Hi picking my through this thread as I’m at the same point, but my question is does the door seal fall outside the Surrey Windscreen Capping? Looking at Tom Frremonts pic it does. But when the Top Cover isn’t on do we just leave the seal edge showing or is there a way of finishing it? My pics below. Thanks

Ian

Hi Ian,

Sadly you should have left the seal protruding at the top, the surplus  can then be squashed under the capping above the seal when it's popped riveted down to make a neat finish.

Sorry :wacko:

Hi Rich,

very interesting to see the elastic on your photos from Sept. 2020

which Stuart indicated on another post about the original TR4A soft top!

Looks like same-same, thank you for that photo.

It’s ok Rich I can still do that, the angle of the pic does quite show the seal protruding above the screen frame, and the pic with the capping on, the capping isn’t fully down, just sat on.

However if I tuck the seal under the capping it pulls it away from the glass at the top.

You need to slit the top of the rubber so the bit that is in the channel goes up under the capping but the flap then continues up to meet the roof (If fitted) thus getting over the gap.
