I used the Speedway Mustang II rebuild kit on my 54 Chevy p/u when I first got my truck on the road. The strut rod bushings only lasted about 12,000 miles and aren't good driver quality at all IMO. They would be fine for a car that was mostly for show, But I drive my truck almost on a daily basis and the parts just didn't hold up very well at all.
I also ordered a new rack and pinion with new tie rod ends from Speedway about the same time I replaced the strut rod bushings with Moog brand parts. When I took the truck to the alignment shop after installing the Speedway rack and tie rod ends, the tech told me the tie rod ends were too loose to align the front end and they were fresh out of the box with about 15 miles on them.
I went back home and called Speedway and wasn't in a good mood at all. There customer service responded with great speed and promptly send me another set of tie rod ends. I installed the second set and got it re-aligned without a problem. But I'm not expecting them to last a very long time.
When I have to replace anymore suspension parts on it in the future they will be Moog replacement parts or a similar quality. They could be made in China too, but the better quality of the strut rod bushings from Moog was very apparent when comparing them to the ones that came in the rebuild kit.
