I've been looking around at adjustable spring plates. I'm looking at someday building an IRS coupe. I found some information about those that have trouble with either installing adjustable spring plates or adjusting/re-indexing the torsion bars and/or replacing the bushings.
There are THREE different lengths of torsion bar, depending on year of chassis or whatever modifications have been done.
The shortest are 21 3/4". Then comes 24 11/16". The longest are 26 9/16" from 1972 and up chassis. The last ones have REALLY long torsion bar caps, and I suspect are the ones that guys have trouble with, and they either have to lift the body or cut an access hole to get anything done.
Anyway, food for thought the next time this comes up for some hapless hobbyist that runs into this.
