Will a 14 bolt semi floater bolt right in to a blazer with a gm 10 bolt?
as far as i know it will,(if you come accross more than one with 373s or 410s let me know ) but what does that tell ya
yes! but, you'll need new ubolts, ubolt plates and a conversion u joint.
It needs to be a 14bsf out of a 80-87 truck. The 2WD and 4WD are different widths as well, but either should work (2wd will be the same as your current 10b, while a 4WD will be approx. same width as your front). Also, I doubt you will find a 6 lug axle in those years if that is what you're looking for. So far I haven't been able to confirm if 6-lug 14bsf were ever made for the OBS trucks, and believe me I looked. NBS trucks came with them, but if you use one you have to move the spring perches and shock mounts (which is what I did).
All good info.
The 14Bsf was first made in 81 and up. The 81-87 version was only available in 8 lug(there is no such thing as 6lug version in the obs), while the 88 and up version was available in both 8 and 6 lug depending on the GVRW, but the 88 and up version had different spring perches, and shock mounts.
Also I believe that you need to look at 3/4 trucks, 3/4 suburbans, 3/4 vans, and 1ton vans. Of coarse with a van rear end you will have to move the spring perches.
Also If you do find a 81-87 14bsf there are after market axel shafts available for it to convert it to 6 lug. This what I plan on doing.
