Re: Vacuum Advance Unit on an early 1974 MGB - adapt to Ported or 3rd party solution?

Hello David
If your car was built in 1974 it would have been fitted with HIF carbs originally. These were introduced on UK and European cars in Nov 1973. With HIF carbs the Vacuum advance is taken from the inlet manifold rather than the rear carb as on HS4 Carbs. The distributor fitted will depend ...

Re: Salisbury rear axle lubricants

Hello Steven
Just a word of caution about the comment “Any hypoid EP90 would do”. This is not correct. You can buy Hypoid 90 oil GL4 or GL5 specification. DO not use GL5 as contains additives that will damage the brass cup washer shims. The EP90 Castrol oil shown in your post is perfect for MGB ...

Re: Drivetrain clunk

Hi
