I'm looking for a set of factory 4" rear blocks from an OBS F350. Let me know if you have anything available. Thanks.

You can buy them new from a few places. I believe procomp makes them. Beware that you don't get a set of worn out ones if you buy used. You don't want them that look like mine. (pic in a minute).

These are the procomps I used. They have a taper to them. I don't know yet if it will cause any problems so I can't vouch for them as a replacement besides saying they physically fit. They are for a newer superduty. Same basic housing.

Surprisingly, I haven't been able to find what I'm looking for new. Maybe I'm doing a poor job of searching.

I'd like to find just a 4" block with the bump stop landing. No taper, and no u bolts since I already bought u bolts. It seems like everything I've seen is a $120-150 kit with u bolts - for that money I'll just make a set.

Used ones really shouldn't wear out unless the u bolts were loose at some point.

Bingo. I'm sure that at some point the bolts were loose on those. I've got a thread here somewhere and I think it was @Dieselcrawler that pointed me to an alternative. As a side note, the ubolts from the kit would not work. They were a touch too short.

Well, I sucked it up and bought new. Feel like a chump for what I paid, but I guess convenience costs. Now I have all the parts to finish the the front 60 swap the way the previous owner should have done it, and I should be able to slam it all together in a day.

Thanks.

sometimes, you just gotta pay for someone else's engineering. sucks that no intelligence was involved. If it makes you feel better, I paid $1300 for my ATS IC kit. after seeing the engineering, I don't regret it one bit.
