Jeep 4.0 in 69 Barracuda
I can not believe I missed this. And with so much money invested. And some pretty expensive re designs with the money spent on the first suspension setup, only to dump it and go with HDK and his solution.
The original OEM starter is 8in long. And the mid line of the starter pinion is directly behind the Idler shaft.
My only option may be to cut the firewall and move the engine back 4 inches.
