gerg 10,871 Posted January 17, 2018 A nice relic to come across, however these are the ones available aftermarket at the time (i came across this a few years ago) back in the 70s. There were a lot more OEM ratios available than these including Chrysler and P76. That list doesn't have the 3.47 1st gear one that my wagon originally came with, or ones that came out after this (like XF EFI)I have read somewhere that even Commodores used them briefly when M21s were on the run out, although in the article these could have been mistaken for the shitty weak non-overdrive BW box.I love single rails and I wish BW develloped a 5-speed version instead of importing the mediocre T5.Sent from my CPH1607 using Tapatalk 1 Slow250XC reacted to this Share this post Link to post Share on other sites
Slow250XC 1,513 Posted January 17, 2018 Good to know Im looking forward to driving the old girl with the rail, shifter feels good as is... not that i pretended to mash gears after fitting the console lol 1 gerg reacted to this Share this post Link to post Share on other sites

EDIT: XE EFI used 302 ratios. The 3.3 in the XE-XF used the notorious "sigma" 5-speed box so is not a 0503 single rail. Some also had a 4-speed version of this box with exactly the same ratios without 5th, but not sure of the application.
