Do MK Engineering balance modified propshaft and if so how much does he charge.

They way it works is you supply a sierra propshaft they modify it (add slider, change length) for 65 quid I think. I don't know if they would balance a pre-made shaft. Personally I would go for a professionally made unit rather than a home built one.

The prop shaft is half manta half sierra as running vauxhall engine I have had it proffesionally done locally just need it balancing.
