Default Front sway bar links

this may sound a bit of a silly question. But I'm going to throw it out there anyway.
About 25 years ago my original front sway bar end links had well and truly hit the end of there lifespan. So I replaced them with parts that most likely came from Ecklers as way back then that's where I was getting most of my replacement parts. (They had much better service back then).
And it's a long time ago but I don't remember thinking they looked different from stock at the time. But I can't be certain.
Fast forward 25 years and while I was under the car doing something else I noticed that the rubber bushings were starting to perish. So I ordered up a set from Zip Corvette.
Now here's where the question comes in. The old ones, But not the original ones have a 1 inch spacer. The new ones from Zip have a 1 1/2 inch spacer.
This will obviously change the angle of the front sway bar.
77 Corvette factory gymkhana suspension, 1 1/8 inch front bar and car is slightly lowered. (About an inch).
Which is correct?
Old link from the 90's.

New links from Zip.

Which is correct???
Thoughts.

The basic idea was to have the ends of the swaybar level with the car at ride-height.
Depending on everything else (changes, springs, additions, deletions, etc) what you'll actually need will vary. I don't believe it's super critical as long as you're close. I'd say having them longer rather than shorter since when they are needed that corner would be loading (sinking)

I can't tell you what other years were but the 77 AIM UPC 3G Sheet 1 shows same part numbers for bolt and spacer used on FE7 or standard links.
My original 77 bolt is 5-3/4" long
Spacer 1-5/8" long.
Spacer part number 3817574
Bolt part number 3817575

My P&A (from 1975) shows the 3817574 spacer is applicable for 63-75. I just checked my originals from my 69 and they measure 1 5/8”.

One other thing to note is that the car should be on the ground before you tighten things down. If there is a significant disparity in their respective lengths, you should adjust the spacer to make both sides match. You are otherwise preloading the front end of the car.

Well, put them in, torqued them up, time will tell. looks to me like very little clearance at full bump to the front frame extensions.
My 20 year old poly bushings.
