From the earlier post "Post Winter Update 2014", I found out during the last TRDC meeting what "The Spongey Stuff" that is falling out around the N/S front suspension spring/strut.
It's a dead UKC1101. Now these are a ridiculous £15 each via Rimmers. However, I'll also need spring compressors at about £35, the spring is rusty, another £20, the shock is only £100 (!), the gaiter is £7 and various other bits of rubber appear to be another £20.
Classic cars are great.
