The plot thickens...

I heard back from the original shop.

I have looked up your invoice to see what all work we did for you. The invoice and paperwork does not show anything about us installing perches on the rear end. We only removed your old perches.
I'm not sure who welded the perches on your housing but we have no record of doing it.
I have attached all paperwork including the note you sent with the housing about what you needed done. Please see the attachments!


I have the same invoices, having saved every receipt for 22 years. Nothing showing any welding/moving perches, and it only makes sense that if the housing were being narrowed, back-braced, ends cut off and rewelded for alignment, that I'd have had them do the perches then! Very strange work

Anyhow the local fab shop removed both, cleaned them up and re-welded them (securely) and I hung it back under the Dart. Next week the chunk will return and I'll reinstall the axles. Hopefully everything will just slide in scope
