Rear Spring Mounting Pad Polybush Kit - Touring spec

What is this rear spring pad polybush kit?

This touring-grade polyurethane bush kit is designed for the rear spring pads fitted between the rear leaf springs and axle on later Austin-Healey Sprite and MG Midget models. It provides a polyurethane alternative to the standard OE-style spring pad assemblies.

The touring compound is intended to retain compliance suitable for regular road use while improving resistance to compression set and contamination.
