Help Needed Sourcing New Front Wishbones

[trd tsport celica1979]

Hello all, im new to celica ownership and this forum, and i need help sourcing parts. I have a 53 plate celica Tsport 190 in lagoon blue, its covered 119000 miles, and after replacing the brakes, all 4 tyres, exhaust, front wheel bearing and all four shock absorbers and top mounts due to it being lowered( shocks taken off a 54 reg celica with 78000 miles), as well as a full service, im left with a really good car except for the front right wishbone bushes have had it. This means i cant drive the at 70mph without my **** twitching like a rabbits nose! Hence i need to replace both front wishbones, and as toyota want £360 a pair without ball joints, and euro car parts want £350 for a cheap pair with ball joints, if anybody knows where i can get a brand new pair at a reasonable price can you please let me know. Another option i have is either replacing the bushes and balljoints on the original lower arms, or buying a used pair of arms, and replacing the bushes with poly bushes and new ball joints. Buying a used pair would make it easier and allow me to keep the car on the road, and just pay the labour to change the arms over. Can anybody recommend a certain brand/type of poly bushes and a reputable fitter in or around the nottingham/derby area? Any help or other ideas are welcome, as i'm trying to keep costs down given that i have just spent alot of cash getting the car to a good condition.
