Diamond connects to the frame which is very Different. You will also need to get a Diamond frame kit, which is much stronger than the Meyer kit. Diamond also uses bigger pins, and has a different connecting design. However you do have the right pump, you want an E 60.
RB, I hate to say this but I would just get a bigger meyers. The diamond plow is too heavy for your gm front end. I had to put $1,500. into my 97 one-ton at 42,000 mi with a 9ft western on it. The front end was junk. My friend has 3 gms with fishers on them and his front ends were junk at 36,000 mi's. My 9ft western was a 100 lbs less than a 8ft fisher and diamond plows are more weight than fisher plows. So I would stay with a lighter plow, your front end will appreciate it!!
GREASE! Grease is cheaper than parts. My last truck saw almost 200,000 km on the original front end before I traded it - and it was the 1/2ton Chev diesel, not the 3/4 ton I have now. The other truck was sold off the lot in mechanically-fit condition without ball joints being R+R'd. Preventative maintenance works - on all brands.
I've had a BOSS V on my 90 K3500 since 1994 and no problems so far with regard to the front end. I don't think that you can get much heavier than a BOSS V-Plow.
Either go with a C-8 Meyer (best choice) or buy a diamond blade and A-Frame and have a good fabricator modify the mounting ears on the "new" Diamond A-Frame to accept the Meyer truck frame. This way you could just use the old Meyer as a backup (not that youd need to). The Meyer truck frame mounts can't be that much weaker, although I've never seen a Diamond up close.
After seeing my First Meyer Plow today. I will say one thing. Don't use the Meyer Frame kit to run a Diamond. It will not take it. It is much weaker, and uses a much different design to mount the plow.
The new MEYER mounts may be different, however, I'd put any plow (withen reason) behind my '75 Burban w/Meyer. How would another plow put more stress on a frame? You cant get more violent than a C-8 4 spring Meyer tripping and snapping back! Weight wise, they arent that different. Mines been on there since 1976 and haven't had a problem with the mounting frame yet...!
Diamond rates their plow at 20 MPH. It uses a tougher A-Frame.
Diamond also uses 1" quick pins, Like Fisher. Not the little wimpy pins that Meyer uses. Diamond has 3 mounting points, However unlike the Meyer blade there are 4 Points of contact with the A Frame to the Frame kit. The Diamond Frame kit also has 4 Points of contact with the frame. However the Meyer kit that I have sean only has 2 points of contact.
You have to understand the Diamond is a tougher plow, the trip edge also puts more stress on the truck frame. You are matching a tougher plow with a Different design to a lighter frame kit, something will give, and not the plow. I am sure you could put a Meyer blade to a Diamond frame kit and be fine. I own 9 Diamond blades, I know the construction very well. After you look at a Diamond close up, or buy one, you will agree that you need the Diamond Frame kit.
Oh yea you will need the E 60H pump to run a Diamond blade, because Diamond uses a different lift arm than Meyer. The regular E 60 won't lift high enough.
You want to look at the Pull A Way system, Not the MDII. The MDII shares the same lift frame as the Meyer plow. However again the Frame kits are different. That is right from the Diamond dealer.
