Newb question. Can i use some of my left over mustang LCA's and UCA's on an 87-88 TC? I haven't seen or measured them, but was curious if i could use left over 4 link parts.

Are the LCA's and UCA's the same length?


Thanks!

I can't remember the difference, but the Tbird arms are longer. Something like +3/4" on lca's and 1-1/2" on uca's? You should be able to find the correct lengths with a search.

Maximum Motorsports makes a really nice set of control arms, with a couple different options.

The following is a good article about using Mustang style control arms on a TC.

There's one thing not mentioned in the article. The control arms are not parallel to the chassis. The uppers are at a rather acute angle to the body centerline and the bottoms are slightly off angle. The mounting brackets on the chassis are spaced and angled for a specific length arm. Using shorter arms will put them in a bind and the bind increases with suspension movement, especially the uppers. As the author states, since he used shorter lowers he had to shorten the uppers to get a decent proper pinion angle. So he ended up with Mustang uppers anyway. I know there are few choices for the T'bird, but use them as opposed to shorter Mustang units.

His angle measurements are wrong also. You want to measure the angle between the driveshaft and pinion flange, and driveshaft and transmission output shaft. The angle between the transmission output shaft and pinion flange is relatively immaterial. It's dependent on relative heights of the two points, their distance from each other, and their relative angles. That's not a good article for adjusting driveshaft angles.
