Well those big ones are the most expensive of the lot. The rest come pretty cheap. Getting local bushings is a big mistake. They never last. That's probably why your suspension is not feeling the same.
I've been working with one mechanic for the past 10 years. His workshop is near the drain when you turn from Ferozepur road to go towards Samnabad. His name is Qaiser and contact is 0321-4206459. If you call him, tell him that Naeem from RED sent you. If you set up an appropriate time to meet him, may be I can join you there as well.
