It is important to be aware that the front wings (fenders) for MGBs are not all the same. Apart from the obvious difference between Roadster and GT, and chrome bumper and rubber bumper, there is also a difference between early and late chrome bumper wings. The gap between the sidelight and the grill aperture is greater on early car than on later cars as illustrated in the pictures below. The change-over occurred in 1968 when the 1969 model was introduced. MGB front wings together with fixing kits are readily available from good MG specialist suppliers.

Before fitting the wing the bodywork underneath must be in sound condition and have been suitably preserved. Follow this link - Bulkhead and Inner Wing Repairs - to visit the page describing these repairs. Before starting it is necessary to remove the dashboard to give access to fixings on the inside of the scuttle. Fortunately MGB front wings bolts-on which makes life a little easier for the home restorer. New fixing bolts should be used and these can be bought as a kit along with the new wing. During the fitting process the wing will need to be trial-fitted several times before the desired fit is obtained. It is important to always fit it and remove it by the same sequence of screws each time. Otherwise each time you fit the wing, it may not be in exactly the same position and getting a proper fit will be very difficult. The wing has a natural leading edge, which should be bolted on first. That is the edge along the top of the scuttle and this is fixed by four 5/16th UNF set-screws with large heavy-duty oval washers fitted from inside behind the dashboard. A certain amount of fore/aft adjustment is possible here. On a Roadster this edge is straight and fore/aft movement is possible. On a GT there is a diagonal shape at this point to clear the windscreen pillar and only a small amount of adjustment is available by the use of suitable shims between the scuttle and the wing on the diagonal. Next bolt on the nine 5/16th UNF set-screws along the bonnet line. Large round washers are used except for the two set screw nearest the scuttle, which should have rectangular washers. The bonnet should be in place at this point to aid alignment. The bonnet is aligned with the scuttle and the wing can then be aligned with the bonnet. Fore and aft adjustment of the wing can be made to allow the front edge of the wing to align with the leading edge of the bonnet. Once this adjustment has been made the three ¼ UNF set-screws with large washers can be put into place down the inside of the wing by the grill aperture.

This then leaves the door and sill alignments. The door should be fitted at this point and aligned with the sill and the 'B' post. There are five ¼ UNF set-screws with large washers, that fit inside the foot-well from scuttle down to sill. These should be put in place loosely and the wing adjusted to align with the door and the recess in the sill at the bottom of the 'A' post. Once the wing is aligned the five sets-crews can be lightly tightened before the final stage. The final stage is to put the three 3/16th set-screws into place along the bottom of the wing. A jack with a suitable piece of wood to protect the wing may be needed at this point. The wing should be carefully jacked upwards to allow the screws to be inserted. If new sills have been fitted it will also be necessary to drill the sill to take the screws. These screws should have an oval washer to spread the load on the wing. When all these alignments fall into place the wing is finally fitted and all set-screws can be finally tightened.
