502 Proline bulldog shell ?

[xfactor]

Calling all 502 owners,

I have purchased a Proline Bulldog shell for my 502 BUT !!! I have hit problems fitting it to the 502.

If i fit the shell so the servo horn doesnt hit the side of the body its aprrox 20mm to short at the back and the back of the lipos are showing.

If i move the shell back so it fits as should at the back then the servo horn pushes the body out at the side.

I have tried 3 different servo horns Tamiya,losi and Kyosho all hit the body.

Has any of you found this or is it just me, I know the 501 and 511 servos are nearer centre of chassis but this is the 502 bulldog shell.

Thanks Guys/Girls............
