dodge has always had a casting problem,inventory situation , on my ww2 VC military trucks,, the motor casting are backwards,, last block in was first out on production line, they didnt care,, just grab one and go. , when a new casting batch came in, it was placed infront of the left over first batch,, then and NOW there is a gap, when production/assemble started over again.. if someone wants to start a excel spreadsheet,, you can track this, with dates, etc.
we've done this with several, wwii trucks/ jeeps, tanks etc,, its interesting to read the data
