Just getting back to my project TJ after Barra Conversion stalled. The Novak adapter will need so extra holes drilled and then have thread tapped. The holes meant for the transmission bolts on the FMax15 do not match up with the holes on manual T5 bellhousing.
The E series bellhousing is better than the AU T5 bellhousing as it has a better casting for the relocation of holes to bolt to adapter. The AU bellhousing does allow lower 4 holes on the sump of Barra to bolt to bellhousing. Before AU they never had the structure to bolt to the sump so this is not really an issue anyway.
Hoping to get the NV3550 trans out of the TJ in the next few weeks and then define location of the holes to bolt Novak adapter to the T5 bellhousing.
