Att: 69 GP 428 HO Automatic Owners
From an old post I do recall there was this reply from Poncho-mike.
QUOTE ** I have a copy of research generated by Fred Simmonds through PHS. It indicates there were 986 428HO automatic trans GPs of which 706 had C60 option (a/c). If so, that would mean there were 986 total, of which 280 were non-a/c cars. I would think not having a/c would hurt the value of a GP, but that's just my opinion. Mike ******** Wondering of those ~ 280 cars how many came with optional 3.90 gears ? I have not seen many and wondering if anyone else has PHS with 3.90 gears ?? Thanx ! |

3.90 gearing w/ HD Safe-T-Track is going to be super rare.
Get a chance would be interesting to see which casting number 8.2 GP r/e housing you have. [QUOTE=Pontiyak]From an old post I do recall there was this reply from Poncho-mike.

Mike Speaking of A/C, anyone have an idea how many of the 706 '69 428HO GrandPrix with C60, were also optioned with Automatic Temperature Control C75???

No..just non a/c cars referring to.
Mine is PHS documented 3.90 HD Safe-T-Track and of course no air cond.
All a/c cars only had up to 3.23 gear. I am curious of those 280 non a/c automatic cars....How many got 3.90's ? |

I will try to dig up the sheet that breaks down GP production. I don't think it will tell you how many automatics were equipped with the 3.90. It did break down close ratio vs wide ratio for the manual trannies, so I would assume the close ratio trans cars got the 3.90. Very few cars were non-a/c.

No Mark
Dave lives down near Chatham Interesting that that 22 69 GP SJ 428 HO cars had M21 close ratio Muncie trans which was only coupled with 3:90 or 4 :33 rear axle. Maybe use some % to figure out that an auto 69 GP SJ 428 HO (even though twice as many built as 4 speeds) 3:90 geared autos would be around 20-25 cars. |
