Rear axle bushes - which ones are recommended?

So I’ve discovered rust and dirt in the fuel system caused a blocked fuel line, and therefore I am going to replace the fuel tank with a new one, which means dropping the rear axle….

so while the axle is out I may as well refurbish it and treat it to new bushes, they look old and starting to crack up, and the beam has surface rust which looks mankey…


what are peoples recommendations please?

I don’t want a harder ride, but I’m not averse to tightening everything up a bit

should I go poly - bush or standard rubber?

 or, should I go with a mix of rubber pivot bushes and poly for the inner/outer ARB?
