MORRIS JB WINGS
THEY NEED A LITLLE (little) WORK BUT NOTHING MANGER (major).
WILL FIT MOST VANS/ICE CREAM VANS
PICK UP ONLY NO POSTAGE.
Starting price is £400, rather high I feel, as Fairmile will make you a new pair for much less than that, headlamp bases might be useful, I know one owner has recently made a pair in fiberglass and another owner is having a batch made in a brass/bronze mix. As we all know a slight knock on the headlamp shell or somebody leaning on it at a rally and the weak Marzack (muckmetal) base cracks.
New pattern Lucas 700 headlamp bowls can be had for about £40 each, check out a kit car parts suppler. Still as the owner quiet rightly states, a rare item.
