Dear Vintage - Opel friends,
I'm pleased to be able to offer you the following article:
central bearing damping ring 'large cih rear axle', Opel rear-wheel drive
The part on offer here fits all 'large' rear-wheel drives with an extension shaft in Opel Manta / Ascona A & B, Kadett B & C, GT. It is an excellent quality part, much like the original rubber.
Combined with a new ball bearing, the rear axle won't be recognisable!
