The driveshaft from base of the flange yoke to center of trans yoke is 9 5/8". I have about 1/8" to the trans boot then it will sqeeze an additional 3/4". Keep in mind I have IRS so the only movement of the trans yoke will be motor movement in the rubber mounts. Motor, bellhousing, trans and differential all connected to frame thus stuck fast. Movement comes from the half shafts.
The trans height does not offer a straight shot to the diffy. The drive shaft is designed for slight offsett using 1310 ujoints. In order to drop the trans low enough to make straight shot I would have to shave bottom of trans, lower trans mount, possibly cut out and lower crossmember or notch it. At that point I would push into the driveway and light her up.....
Then buy a KMS....
This set up will work just fine...
