Default 70 gto bucket seat stops

So I noticed 1 of the rubbers was missing on each of my bucket seats. Ordered a 4 pack. The ones sent are almost twice as thick and you can see mine have a 2 where the replacements have a 3 ,,, not sure of the significance of that. Do you have the thinner ones?

With the thicker stops if I let seat back normally it won’t latch and if i push the seat back to latch it won’t unlatch by the button unless I push back on the seat again.

scott70, I apologize for the trouble you're having! The measurement we have on file for these bumpers would be 1.45" x .85" x .51". Please compare and let me know.

Thanks!

I have pulled all different thickness off of 69-72 seats,
some
even had stacks of oval washers under them
I have a dozen of em I have raided off of core seats

what thickness do you think you need

I feel depending on the assembly of the seat it requires different stops to
or for the seat back to be positioned correctly

I have a pair of buckets right now original covers,,, only 3 bumpers.. pass side
only has one ,,, no witness marks of bumper ever there no less a screw hole

The thin ones look like the ones on my 1964 GP bucket seats.

Maybe during factory assembly there was a few different thickness bumpers and they used whatever worked best for the particular car. IDK. Like I said with the thicker ones installed I now have to push “back on the seat to get it to latch and unlatch which I’m sure was not the way it would have left the factory. I will take a mic and measure the thickness of my original ones. If the replacements are .51 I’d say my originals are 5/16 to 3/8”. In the pic you can see what I noticed the other day,, the rubber had fallen off one leaving just the metal backer. It was like that on both seats.

Basically the length and width are the same but my original thickness is like. 34-.35 compared to the thicker ones which are .500-.510. The inline tube ones are also the thicker ones. I guess no one sells the thinner ones.

I ended up cutting these down to .440 -.450 so it latches and unlatches with minimal play in the seat.

Thank you for continuing with the thread and keeping us updated! I will make sure to note the differences we've seen here for any future questions.

Thanks!

Compare the size of the earlier ones. They may be the correct thickness.

careful bumping of bench mounted belt sander out to do the trick to take a little thickness off.

I used the Ames bumpers on my 68 and had no problem with the seat back latch.
But my buckets used only one bumper per seat, mounted to the inside. I don't know if if that was another Fremont oddity or was it common for 68?

I used my standup table belt/ disc sander. The rubber is somewhat soft so it didn’t take much to remove material. I practiced on one of the inline tubes one and took off too much. Had to sneak up on it. For the fine tuning I didn’t run the machine and just rubbed it across the belt.If the seat is a little too upright I can always remove more material but it’s hard to put it back on.

All 3 of my '70 bucket seat sets have .50" +/- 0.02" heights. Have a molded 3 and BI-199, maybe more. I read there are repro. ones measuring 7/16" (Maybe search 7712536).

Maybe theres some variables during assembly and they put in what works. Like was said the .50 is a little too thick for my seats to work correctly so maybe they threw in the next thinner ones (#2) . But it sounds like the majority might of been the .50 pads. Learn something new.
