The 62 lower inner bushes should be OK as far as general wear goes, unlikely to be the original ones but they do last well. This was the first year of the B18 and the design was changed from the earlier B16 cars. They did have weak bushings as these lower ones were the same rubber cotton reels as used on the top A arm. The lower arm changed in 1964 but used the same metal cased bush. If you're considering poly, the top inner ones area good place to put them. The rubber ones supplied now #87033, aren't as tough as they used to be. Poly bushing the anti roll bar and rods also a good idea.
