I assume you cleaned and painted engine, starter, etc. How about scraping off some of the paint where the starter mounts to the engine. Ensure that you are grounding to a clean, bare area and that the cables you are using are of the correct guage. Inexpensive jumper cables may not be able to handle the load, and paint is not a good conductor. One more thing to check, is the valve lash on spec? If valves are not opening correctly, that could be an issue.

I have purchased several items from Bob. Always got good parts, prices and service. Hope everything is ok, he is one of the good guys.

They have a separate part number for 4.55 ratio as well. Must be the speedometer drive on the mainshaft.

Don't disagree with special order ratios. Do disagree with statement that 4spd was only used with 3.07 ratio.

Are you sure about the 3.07 axle? IIRC, standard R/A was 3.73 for 63 and 3.54 for 64 for cars with 4spd.

Yes, Shims on right side, followed by brake backing plate, followed by reinforcement plate, and finally, the dust seal. IIRC, there is a thin paper gaskets that goes between the dust seal and reinforcement plate.

The 2 piece pin pictured, aka thrust block, is for twin traction. The open differential uses a one piece thrust block.

FWIW, picture of correct rag joint with horn jumper.

Pictures of 78 Avanti Spring spacer. The Studebaker Spring coils are flattened on the ends. IIRC, the 78 coils were round.

One on each side. I have a spare set. I will post pictures later this morning.

My 78 has two aluminum spacers on the bottom of the springs. They are about 1/2". I did not have any rubber spacers. I do not know for sure if this is factory.

Just to ask the obvious, did you check trans fluid level?

Love it! Much better than the 4 door.

I am looking for a usable pair of parking light housings for my 64. I believe they are the same up to 84 or so. I have purchased a pair of the bronze repops from Dan Booth, but would prefer OEM.
