I've seen to many ads stating 100% complete when in fact there was plenty missing.... Put knowledgable eyes on the Dana before value cause lots of 8.75 axles have been called Dana & worse yet a an 7.25 has a rear cover so some folks think thats a Dana....
Hemi 4 speed might be $1000, but a 23 spline is $350ish... Put hands/eyes on the shifter, clutch linkage, bell housing, driveshaft.....
If you want to be upside down jump in, personally I've put enough cars back together & don't need the experience, If you love the combo buy it but know that you'd be money ahead to buy a running driving car....
Or send it to Alan.... He needs more work...
