TA's don't match

[sail]

Off my 4A the left had 74TR6 handwritten and the right TR6 in a different pen. Left a Stanpart logo right none. Casting differences, spring cups, stop platforms, size of brakeline attachments are some of the differences.

They have gotten along so far and are going back on.

These cars were like Goulash. (Or Bill's Gumbo)
Throw on what was on the shelf.

There was an early and a later Trailing Arm for these and I never knew what the difference was. It looks like we've cleared that up.

These were probably taken from two different cars and sold to whoever replaced the one on the left as being correct for the TR4, when it is obviously not.

The one on the left is just like my 74, but the hole in the center of the (+)is filled, which means you'll have to drill that out to install the rubber (cushion) bumper in there.

I have a stack of them, if you want to match a set let me know which one you want. PM me -$25 and shipping.

Bumper goes on the body.

Thanks these will do but I'll keep you in mind, I'm sure something else will come up.

On a TR4A, the bumper is mounted on the body so that's why they filled it in. This is interesting to see the differences since except for the bumper change, I didn't realize they had made other changes as well such as in the lower spring area.

SBC's were meant to have solid axles.
When 'they that designed things' wandered from this creedo they ended up creating complicated and weird parts when simpler proven designs already existed.

 

[Brosky]

I kind of figured that the bumper went on the body when I saw the design of the arm on the right. However, having a bumper on the body with a raised 2"-3" section for a later style bumper to mount, will not give much clearance or travel in that side. That later arm should not be on the earlier car with the frame or body mounted bumper.

I should have taken a picture of one of my spares to confirm what I meant. I couldn't tell from your earlier pictures, but it is now obvious that someone has shaved the bumper mounting area on the arm on your car down in that spot.

Brosky I see what you mean and once looking for it could see where they did their handywork.

Rich,

If they hadn't you probably could not have a bumper on the frame. If you can get your matching arm, you will better off in the long run.

I'm a little fond of my TR4A IRS cars and my wife's 1968 Spitfire was a blast as well!

Didn't Triumph produce more IRS sports cars than non-IRS ones? :wink:

[Andrew Mace]

Considering there were over 300,000 Spitfires alone, probably!

LOL!
