    May have one. I know I have a 243, but not sure of the year. I'll check tomorrow.

    I know I have a 7040245. May have some 243’s in this last purchase. Still going through them all.

    I think a 7040243 was on 70 Riviera 455 with standard transmission. The 7040245 was for a 70 350 S/T.

    7040245 is definitely 350 manual transmission - took me a while to find one. I believe 7040243 is a std. 455 manual transmission.

    I may have a 7042942 MF 1752, but you would have to wait till OCT. before I can get home to check....

    Yea standard 455 4speed carb, I have one I'm putting together for my X. Exact same carb as the Stage 1 carb from what I can tell, same calibration and top lid as the 0246

    Mark, what's the date code on your 0245 carb? I can't imagine there were many batches of them - 243 & 245 were probably the rarest '70 carbs made.

    Sorry I’m late responding.
    The 7040245 we have is a 1089 date code. 350 4 speed. Very early date. It was the engineering master carb used for testing prior to production.

    And George, we don’t have a 455 4 speed for 70. We still have about 600 to go through. Will let you know if we find one.

    It's fine - you had told me in an email that it was engineering master carb. but thanks for the follow up. I was just curious to see, like we have known build dates for 246's, if I could piece together known dates for 245's (mine is 3239) which unless there were a bunch of manual transmission 4-BBL Skylarks or manual transmission LeSabres (I think all 350 LeSabres were 4-bbl?) is probably rarer than a 246. The 243 George needs may be the rarest of all again, depending on how many LeSabre 455, Wildcat, Electra (?) or full size wagons came with manual transmissions.

    Gotta be one out there somewhere.

    What kills me is the ones in the past that sold on this board for short money. I was lucky enough to find other 4 speed carbs- like a 73 4 speed carb, a 69 4 speed carb.. Just no 70's. No biggie. I will find one eventually ;)

    We know rare doesn't equal valuable - I paid 1/10 the price for my 245 as I would've for a 246 but was sure glad to find one.

    Also curious to know what the first batch/run of the 243’s were dated. I have an early car,built the second week of September/69.
    Should be in the early to mid 200’s for julian date.

    This was what was shared when I purchased my car back in '96. Am I on the right track for my 1969 GS?

    Thanks, Mike

    I paid $50 for a 72 Stage 1 carb in BG. Talked him down from $60. No joke!
