Hello I have a perfectly serviceable Mgb wiper motor with tubing & wheel boxes etc and wondered if this is possible to adapt for my Hawk 289 build - any advice on this would be appreciated
I would also be grateful for the dimension between the wheel boxes
Thank you

Re: Wiper Motor
Hi Chris, Its a long time since I built my car and can only advise that I used a 2nd hand wiper assembly and had to adjust the tube lengths to suit.
Distance between wiper arm bosses measures 520 mm ( 20.5") and arm travel approx 120 degrees.
I have seen another posting on the forum recommend 130 degrees.
Maybe someone else can advise the correct gear you need which will give you the correct stroke.
I can't see any reason why you can't cut adjust an MBG assembly to suit.
Hope that assists.

Re: Wiper Motor
I have just come across the build manual.
Wiper centres are correct at 20.5” and should be marked on the body work.
It confirms a 130 degree drive wheel is needed plus mentions getting hold of a longer rack thus inferring that a standard MGB rack might be a bit short.
It also mentions a Lucas 72891 wiper boss is ideal as it has a longer stem to allow for the thick fibreglass.
Maybe I was just lucky I had a suitable set.

Re: Wiper Motor
Many thanks Peter for your replies.Even though I have the build manual (kit due March time ...?) there doesn’t seem to be much info on this.My elderly father who is an engineer by trade and definitely ‘old school’ wants to adapt the mgb motor and make a mock up to check the sweep etc
