Technical Pinion angle on open driveline conversion

Hi
So I have I have 53 Chevy sedan with torque tube. I have 55 tri 5 Chevy rear end , do I need to mess with Pinion angle? Or just redrilling spring perches 1.5” forward is enough??

 

A 53 what and a 55 what?

 

53 Chevy Bel air and 55 Chevy tri5 rear end

 

Drill the spring perch for the offset centerbilt and your golden .


Post pics of your car, we like pics

 

Of course you need to verify the correct pinion angle, after assembly. If the 55 spring mounts are the right width for the 53 springs, then I'd redrill the mounts and bolt the thing up. Then check the angle and adjust with wedge shims as needed.

If you need fresh mounts on the axle, verify before welding them on.

Every car will be different because the engine/trans might be at a different angle.

 

Photo of my axle in lol thought would get away from pinion angle settings.
