I have a Motorlita wheel fitted to my 1979 Spitfire.
I bought this from the club shop and it came with a generic mounting boss. This works perfectly well, but does not have a Triumph logo.
I thought I would buy a boss from Motorlita and get the correct badge. The boss has arrived and won't fit. The splines seem to mate OK, but the base of the unit is too wide and fouls the steering column shroud.
Motorlita list two bosses for the Spitfire. The one I ordered is 48 spline diameter 19.04 mm. This is for 1979 on models. The other is for up to 1978 and has 36 splines, diameter 15.90 mm.
Can anyone tell me which size of spline my car should have? i have also asked Motorlita for their comments.
The club shop no longer stocks the wheels and can't help.
Thanks in advance for any assistance.
