1967 F40 rear 7 leaf spring spacer

[Guest]

On 1967 F-40/41 rear 7 leaf spring was there a small flat spacer that went under differential then the spring was bolted up to it

Just tighten the bolts up and then snug.

Don't believe there was a spacer.

There a small plate about 6 inch long as your first leaf or spacer it not much of a leaf look like a spacer

Re: 1967 F40 rear 7 leaf spring spacer

It almost looks like someone cut the top leaf as there are only 6 leaves on that one you pictured. Or it may be a non original and someone added a spacer to get proper overall thickness.

Here is a '67 F41 for reference.

Rich,

Is that Lonoclad (the gray) you painted the leaves with or is that just gray paint trying to reproduce what was never there? Or just maybe trying to keep them from rusting?
The Lonoclad was applied to the bottom of the spring leaves to possibly stop noise? Never thought too much about that. Thought the liners were there to keep the noise down.
You just trying to simulate the sloppy work done by the St. Louis workers I guess by painting the entire spring?

Service HD spring I purchased from GM SPO in the 80's came with that extra spacer. Not sure if that was production for later years. Left it off for my 63.

I wonder if they included that spacer due to thinner leaves and to ensure original length bolts would not break the differentials.

Jr, No just Rustoleum gray to protect, not meant to be "typical". Hmmm, sloppy? I thought they looked kinda "concours". It did get a hit in judging of course.....too "shiny". Of course the sheet said NTFP.

That looks alot better thanks for sharing the photos Richard, was just wondering about that top spacer if it was factory or not and also didnt they remove the plastic liner between leaf 6 and 7 on the F40/41 spring by NCRS judging standards.

Good info Gary Thanks.

I see the 354130 was a service replacement for 1963 to 1975 with HD Suspension(here). Maybe my hunch was right about overall thickness and the 0.306" top plate was added to match original thickness.

Re: 1967 F40 rear 7 leaf spring spacer

So it safe to say there was a small spacer on top plus 7 leafs on a 1967 corvette for the F40/41 setup Gary

Danny, No, original 67 F41 7 leaf assembly line installed rear leaf springs DID NOT have a spacer. The bolts were shorter than 9 leaf bolts. Jeff
