I'm currently restoring a '72 Dart and I removed the 8 3/4 housing for sandblasting and paint. My friend returned the finished housing to the shop however he put the restored housing with several other UNMARKED 8 3/4 housings. There used to be a diagram in the tech archives with various measurements however I can't find it. Can anyone provide me with a site or tech. archive info. concerning the measurements(flange to flange, perch to perch, etc.) so I can finish my project?
