Volvo Penta produced the AQ series right along side of the SX and DP-S style drives from 1993 up until approx 1996, if memory serves me.
From what you are describing (short vertical shaft -vs- longer vertical shaft), may I assume that this is an AQ series drive????
Which one does it ressemble?
This is an AQ series DP-C 3 pc drive.... the good stuff!
This is a DP-S drive!
After the AQ series "C" drive, the lower unit vertical shaft becomes shorter, and requires a long vertical shaft spline coupler (aka splined sleeve).
Shown here is the short coupler SEQ #12 for the longer and earlier lower units.
If you have the AQ series 3 pc drive, any swapping of either Transmissions and/or Lower Units requires "Re-Shimming". The lower unit vertical shaft roller bearing race must be re-shimmed.
This is not an option..... it must be done.
Also note that your 5.0L engine dictates that the 1.95:1 ratio be used.
Post back with which drive you have.
