I've noticed in some parts catalogs that they refer to an early and late model for 70 GTO’s for some parts, what is the date that separates them? Thanks

[mechanic17]

Don't know--mine is very late (june) and never found a difference.

Back seat ashtrays? I have a really early 70 and they have the ribbed lids like a 69.

Red or black PMD center caps and chrome or black knob on the bucket seat adjusment lever are possible differences.

[GTO_6970]

A/C compressor brackets and fuel pump are possible differences.

The parts I've purchased over the years that asked if it was an early or late car were the fuel pump and fuel line, and this week it’s the power steering hoses. My car is an April built car, is that considered early or late?

What is the date that they use to separate the early and the late versions?

[GTO_6970]

I read somewhere that January/February was considered the transition period from early to late. That may have been someone's opinion, however, and not fact. My '70 vert is a February build and I used the late fuel pump and lines (seemed to have more availability), early A/C brackets (because I like the looks of the aluminum bracket versus the steel) and red PMD centers. I ended up using an early power steering hose (same as '69, I think) because the late hose that I originally purchased didn't seem to fit very well. The power steering hose fitment may have been due to a poor reproduction and not the original design being at fault - I don't know.

In general, this is the time period I use (although I cannot speak to the '70 model year specifically).

So ribbed ashtray lids of early production are the exact `69 lid or slightly different?

Yes. They probably just used the one style until they ran out.

[SteveGB21]

On Early Models, it is anything from August '69 to January '70.
Late Models are from February '70 to July '70.

Again, I forgot the source, but that was what I read.

My Sept. 70 GTO had a console lid without the lock and it had the 69 style parking lamp fasteners.

So if my '70 GTO has a 06E build date, that means that it's a very late build date for the 1970 model year?

Yes, your car would be considered as a late 70 GTO built 5th week of June 1970.

Isn't mid-'70 when they changed to the long-snout water pump? That necessitated a deeper WP pulley to fit with the existing belt alignment. I have one of those pulleys on my '66 which also has the modern long-snout pump.

I've had my 70 since May of 80. It was delivered in January to Colonial Pontiac in Miami. When I got it, it didn't have the original rims (Cragers) so I don't know what color center caps it came with. It did have the alum. A/C compressor bracket though. I always figured, since it was delivered in January, I could get away with early or late stuff.

I have a '70 plain jane (no A/C, bench seat, auto on the column, painted that ugly mint turquoise color) GTO that I bought in early 1986 from the original owner's son. He told me the carburetor had been changed (it was changed to a factory service carb), as well as the water pump. In looking at the replacement water pump on the car, it has the correct casting number but a Feb 70 date on it (my GTO is a Fremont car and it was built in the 5th week of October 1969). I found and now have a water pump with the same correct casting number on it but with a date of late September 1969. The two water pumps (Sep 69 and Feb 70) are identical.

I've only heard this but there is an argument on one side that the Rally II center caps were black all the way to the end of the 1970 production year. Another side will say that late production 70s with Rally IIs got red center caps. I've never been able to determine, one way or the other, which it is. If the assembly plants ran out of black, though, I suspect it would have been very late in the production year.

I'm not sure what a ribbed ashtray lid looks like. The ashtray lids in my car appear to be smooth to me.

My Pontiac built 09E car has JL wheels, Black centers, 69 style horn relay cover, smooth ash tray lids, Lightweight WIDE mount rear spoiler, and did not have the chin spoiler. I think the WP is the long snout(4.5"), but I need to verify.
