Firstly, I must apologise for invading your forum as I own a 1960 Austin Healey Frogeye rather than a Mini, but despite my best efforts I haven't got any response from the Midget and Sprite Club regarding my query.
My question relates to A series Spares who I know you have had some not always happy dealings with and an electronic distributor I bought from them in 2017. I need a replacement side entry cap but the standard 25D cap appears not to fit it and I've also tried the 45D cap too, to no avail. I contacted Imperial Nuts and Bolts as they still appear to be selling the same units, at least the description looks to be the same and sent them a picture, they went away to check but never bothered coming back, ditto The Distributor Doctor.
Has anyone fitted this unit to their Mini? If so, could you point me in the direction as to where you might find a replacement cap that will actually fit. I didn't really want to junk a relatively expensive and working unit for the sake of a cap and I am getting to the point of mild despair.
Thank you for your help
