Can't find definite answers besides they are rare... I'm assuming they only came in the diesels but havnt got into major research yet! anyone know of a full float 14 that'll bolt into my 99 burb? The 14sf in it now have g80 and I'm pretty sure it's going bad bc I had some clunking in rain and been a vib that we'll see tue if it's bearings or g80 just looking in advance! I know I could put perches on older 14 but wanting to just pull and replace! Thanks
 
yes it will... I did the same with my older truck... Swap from 14 SF to 14 FF keep in mind the 2wd is different from the 4wd, so look for the same/similar truck 2wd or 4wd and swap. For me it was a complete bolt on, took me about 2 hours (back then).
 
14 ff came in the big block 2500 suburbans. Mine is 4:10 I have one each if you need a particular measurement.
 
Ok cool mines 4.10 also but small block! Gonna call the junkyards I suppose not many 2500 burbs in this area that I've seen for parts
