A front spoiler is not only there for looks. It can aid stability and improve cooling, especially at high speed. It is possible to get front spoilers of various kinds to fit models such as 510, 610, 710 and B110. These usually have to be sourced front the USA or Australia. I bought this particular one for my 1971 Datsun 510 off of eBay from the States. Fitting it is fairly easy and below I give a step-by-step of how to install it. Of course not all spoilers will be the same built this type of spoiler, often called a “spook” is pretty popular so these instructions should be relevant to the majority of installations.
The first thing to do is to attach the spoiler and check for fit. It’s relatively easy to clamp the spoiler to the front valance with a couple of pairs of vise grips. Now is the time to do any trimming if neccesary on order to get a good fit.
Once you are happy with the fit and have the spoiler nice and straight and level, take a black permanent marker pen and mark a line along the underside on the front valance. This will allow you to get it back in the same place easily when fitting it.
Next, you want to decide where your mounting bolts are going to go. Make sure they are not going into closed sections or an area where it would be hard to get a nut on the rear. When you have decided on some locations mark them with your marker pen.
Now take the spoiler off and drill the holes. For this I used a 6.5 mm bit. Although you marked the holes on the uderside you will have to drill them from the back of the mounting lip. Make sure you don’t drill them too close to either the edge or too tight into the corner, otherwise it may be difficult to fit the bolts.
Once the mounting holes are done take some coarse abrasive paper and rub along the underside of the lip. This will take off all the errant strands of fibreglass and make it easier to fit the bolts.
Now, refit the spoiler back to the line you marked. Once in place you can mark the position of all the mounting holes. It will probably be impossible to mark them through the holes you have just drilled so a little guesswork is required. It’s relatively easy though… just mark the positions of the holes below the marked line then with the spoiler removed you can mark the hole positions about half an inch above the line all the way along.
Now the nasty bit! Get your 6.5 mm drill and drill the mounting holes in the valance. It may help if you use a small center punch to mark each spot with a small dimple. Once you have drilled all the holes put either some paint or better still, some waxoyl on the bare metal.
Now is the time to paint the spoiler whatever colour you fancy. Once prepared, clamp the spoiler back on again, aligning it with the holes. There are a variety of methods you can use for fixing the spoiler in place. You can use self tapping screws and spire clips, screws and nuts or even the plastic nuts and bolts for holding number plates on.
I decided on using some 6mm zinc coated nuts and crosshead machine screws. Fit all the screws or bolts before tightening any. Carefully tighten them all up and then protect them from rust with a little more waxoyl.
All done! I decided to paint mine matt black in order to keep it subtle and make repairs easier. Just as well as the first track day after fitting it I ran over a cone and cracked it …doh!
