Front Lighting

The IVA test requires that the front indicators are no more than 400mm from the outside edges of the car.  On the Avon this would be measured in from the rear wheel arches (being the widest part of the car).  The rear arches are 1750mm in width so the indicators need to be no less than 950mm (1750 - 800) between their outside edges.  As with most sevens the indicators needed extending on stalks.

I found a plastic waste overflow pipe at B&Q which is the perfect fit to hold the motorcycle indicator units.




To create a fixing to the nose cone of the car I used a 22mm copper pipe blanking cap with a M8 bolt.  An 8mm bolt was used as this is the same as the indicator unit bolt.  The centre of the bolt was drilled out to allow the wires to pass through.  A length of rubber sleeve was used inside the bolt to prevent chafing on the edge of the hole.

As well as using glue a couple of 3.2mm rivets were used to lock the bolt in place and prevent it spinning when tightening the nut.  Finally, prior to fitting, a quick coat of black paint was used to cover the copper and rivets.


To allow more clearance on the cycle wings I've changed from the 5 3/4"  light units to the smaller 4" Dominator motorcycle units.  Being smaller they should reduce drag (a little) and boost the top speed (a little).

The wires needed extending and protective sleeving added.  The colour scheme for the wires was very bizarre.  I had to trace each one to the bulb holders to work out what was going on.  After the bullet connectors were attached I labelled each one to prevent future confusion.


Being a motorcycle light the Dominator has a flat beam pattern, with no kick-up to the left.  This is fine for the IVA test, but to help it pass the MoT the light unit is best rotated a few degrees to give the required kick-up.  To do this a second locating cut-out was filed, to the right of the original one.  This causes the whole light unit to be rotated anti-clockwise when viewed from the front of the car.


Front indicators and headlights mounted and wire in.  I'll replace the bullet connectors with soldered connections after the IVA test.  I've ordered some proper two pin connectors from Ebay for the front indicators.  This will make it easier to detach prior to removing the nose cone.


I had some black card handy in the garage so I thought I'd use it to check the beam patterns.  Here is the dipped beam.  Hot spot in the centre and kick-up to the left.  Hopefully good enough to please Mr (or Mrs) MoT tester.


And here is the full beam.


These are small light units and are mounted quite low.  As such their beam will be masked partly by the front cycle wings.  This should not be too much of an inconvenience as they will really only be used to get home around dusk.  I don't plan to be making too many long distance trips at night.

Seats and Harnesses

Intatrim Ranger seats have been installed in the car along with the Tiger provided harnesses.  I decided not to opt for colour coded piping on the seats as I think there is already enough contrast with the red harnesses and red detail line on the wheel rims.  Also, I was a bit worried that light coloured piping on the seats would quickly discolour.  That said I'll have to make sure only clean hands handle the red harnesses.


To mount each seat four M8 cap head bolts were used with nyloc nuts.  Bolting through each of the two lengthwise chassis rails and fitted with load spreading washers inside the seat and underneath the car.

Interior Trim

Originally I was going to go for the 'stripped out racer' look, but in the end I changed my mind and bought the interior trim set from Tiger.  This consists of a centre tunnel cover, carpet for the rear bulkhead, full length fitted floor mats, gaiters, aluminium and vinyl for the outer cockpit sides and carpet panels for the forward tunnel sides.

As I have the Rally Design gear remote I needed the hole in the tunnel cover for the gear lever to be further forward than normal.  I posted Tiger a paper template and they made up the tunnel cover to fit.

First job was to cut the aluminium side panels to size.  Once one was trimmed correctly it could be used as a template for the other side.  A piece of vinyl was cut and attached using contact adhesive.


The end result has turned out quite professional and looks really good in the car.  The panels themselves were fitted using black pop rivets.  A little silicon sealant was added on the runs between the rivets.  The idea here is to try and minimise any vibration of the panel when the engine is running.


With the carpet glued, using spray carpet adhesive, to the rear bulkhead and all other trim items in place, the cockpit starts to look really nice.  I need to get an angle welded in the gear lever (to clear the dashboard) before I fit the gear lever gaiter.


Next will be fitting of the seats and harnesses.

Rear Lighting

All fitted, wired up and tested.


Some of the wiring could be attached to the chassis tubes, but inside the wheel arches there is nothing to attach the wires to.  Some Grip Fill was used to glue clips to the inside of the wheel arches and then cable ties could be used.  Sprial wrap was then added to all wires to prevent chafing, particularly where the wires pass through the fibreglass.

As the fog light needs to be vertical for the IVA test I used one of Tiger's fibreglass 'wedges'.  I didn't need to use them on the rear light clusters as my light units are tapered at the back.  To mount the wedge I made up a small bracket.  I made sure the holes in the bodywork are the same spacing as on the fog light until, so in theory I can attach later without the 'wedge'.
