[POOR MAN RICH]

Hey Guy's, Newbie with a question. I was wondering if someone could tell me what the codes for my rally wheels should be on my 1971 1/2 GT-37. The car was built in Pontiac MI in April of 1971. Thanks PMR

Welcome to the forum PMR!

The wheel codes for your GT-37 are JT for the 14 x 6 Rally IIs and JX for the 14 x 7 Honeycombs. 14 x 7 Rally IIs were not available for the GT-37 in '71.

[POOR MAN RICH]

Thank's gtoric, I have a set of JT's, anyone have an idea what the date codes would roughly be? PMR

[PonchoV8]

No, but I need a set of JTs for my car. 70 car built first week of March.

What are the numbers by the valve stem on yours? One large number on each side of the stem. What's the build date of your car?

[POOR MAN RICH]

Poncho V8, The build date is the fourth week in April of 1971. I don't have the wheel's at home so I'm not sure what the date codes are I just know they are JT's.

The '71 Pontiac plant cars continued to show JT as the wheel code on their build sheets long after JT's had quit being made & used.

The correct 14x6 Rally II wheel for a '71 1/2 GT-37 (or any '71 Pontiac with 14x6 wheels & produced this late in the production year) will be a KU. Check the dates to the lh & rh of your JT's valvestem. I bet they either date a much earlier matched set OR are a pieced together set.

[POOR MAN RICH]

OPH, I went and checked my wheel dates you are correct they read 0 3 19, the 0 has the letters MI over the top. I'm assuming this read's 1970 March 19. Now I know from lurking on the board that you seem to know alot about wheel code's, but if one took his car to a national event and had concourse judging done on the car would they know that the car came with KU code's instead of the JT's that the build sheet calls for, or would they just know by looking at the date's? Thank's for the info and any you can give me P.S. I aquired these off a 1971 Lemans that came from the factory with hubcaps it is a matched set. PMR

[PonchoV8]

A little late for mine. Figgers. Still interested in them though, if you find KUs are gonna be needed. I might have a couple.

PMR, Not sure how smart the judges have become at GTOAA & POCI Nat's in respect to concours judging with the '71's & 72's. Can say, in the past, their lack of indepth '71 & '72 knowledge has resulted in less than stellar results when it comes to this era of car being propperly judged.

Can state with 100% certainty, that KU's are correct for your car, if it came with Rally II's & not 14x7 HC's. If same car was a very early '71 GT-37, it would have come with JT's like my '71 Judge. Personal research on Rally II wheel codes just so happened to start in the mid 80's with aquisition of a certain '71 1/2 GT-37... an Adriatic blue 455HO M40 car, built less than a month before your car. After parting on hundreds of '71's & having come up with a large stack of '71 buildsheets, can state the KU coded Rally II was introduced in the Fall of '70 & was carried into the '72 model year. In '72, the KU was mainly used on Ventura's while '72 LeMans (equipped with 14x6 Rally II's) receieved KT's. Hope this helps, if you like, will keep an eye open for a set of KU's that date your car. I have had dated sets of 4/11/71 KU's in the past & am always buying & selling or trading early Rally II wheels.

[POOR MAN RICH]

Poncho V8, I know how you feel... I had hoped the JT's were the ones I needed. For right now I'll hang on to them and see if I can find a matched set of KU's. If I cannot find a matched, proper date coded set I see no point in getting rid of the JT's.

OPH, I can see where your coming from on the concours judging, don't know if my car will ever make it to concours, but would still be nice to have the original wheel's that belong on my car. Guess I just hoped mine needed the JT's.
Mine did leave the factory with Rally II's. If you would keep an eye open for me on the KU's that would be great, but if I'm going to bother I would like a matched set. Thank's for all your help, I have seen a lot of the wheel code threads, but never really much detail on the 71's. Also what date's do I want to look for just incase I run across a set?
Oh yeah, and that "certain '71 1/2 GT37" was quite a needle in a haystack you found there. 1 of 54, not to mention how desirable the 455HO car's are, and then a '71 1/2 car . I have seen a few '71 GTO's in the Adriatic Blue beautiful color, what color stripe does your's have? Also has anyone broken down the number's by transmission? I know my car is 1 of 572 just curious as to how many were 3 speed's.

What's the build date on your car?

[CraigGT37]

Poncho,
My build date is an early model,09/02/70

[PonchoV8]

Poor Man Rich, I discovered that I have a set of KUs today. Haven't looked them over real well, but they appear straight and should clean up if you wanna trade the JTs.

Just stumbled on your posting and was interested and thought I would share that I have a 71 gt-37 much like yours it is a lucurne blue 400 3-spd with black int and a brench seat. I just finished doing it over, It is not entirely stock but not far from it. I have put a 4 spd and a fairly stout 455 in it, and I am running 15x7 steel wheels and poverty caps. I will probably switch the wheels around for my entertainment later.

Ol' Pinion head,

Just curious, have you done any judging for the GTOAA or POCI? You do have an opinion on the quality of their judging, so you must have participated in the process at some point, either as an owner or an observer.

"Less than stellar" judging results can only be improved upon by employing "more than stellar" judges. Both of those organizations seek out qualified experts for the judging duties at their national conventions. Unless you don't belong to the clubs, don't attend the conventions, or have some objection to these group's activities or direction, you should think about volunteering to be a judge.

By the way, were the KU code Rally IIs added to the line with the introduction of the Ventura II and then released to the A-body as well? Does the KU installation on A-bodies only apply to units assembled in Pontiac?
