If you have a list of thread size by grip length, check out Allen's Fasteners.
They sell individual ARP bolts, and have a great website for listing bolt lengths.

Many times I've started out to do just that, go thru the front dress bolts bolt by bolt and develop a list of p/n's that I could order from. Each time something more important comes along and.....

Can buy the FSB's front cover bolts & studs from LMR, that solves most of those needs. Would be better if it were fully complete with all of the front dress bolts. Maybe just knowing that kit is available plus the couple other needed bolt's p/n's is enough?

If only there was a tech write-up to answer all these questions...

Not ARP, but I found these the other day:

ARP 1541504

Look at the LMR link, it is specific rather than generic.

In general SS hex heads are roughly SAE Grade 2 in strength. There are exceptions, but you aren't going to find them at a typical hardware store.

 

[dmoses42]

Ok, for ARP (you will end up with extras):

651-3250
651-4000
651-4250
651-1250
651-2250
651-2000
651-1750
200-8587 (need two kits)

^^^
Once this is confirmed it should be added to the write-up that Viper linked.

 

[dmoses42]

Let me reassess... I thought I used Viper's post when I pulled my numbers, but when I just rechecked the numbers I posted, they are all 5/16-18. His post has 3/8 and 7/16 bolts for the brackets. Standby...

 

[ntsqd]

I skimmed the article looking for p/n's for bolts, but I must have missed that section.

 

[dmoses42]

Ok, the numbers I listed are just for the water pump and timing cover. Let me look up the numbers for the accessory brackets....

 

[dmoses42]

I skimmed the article looking for p/n's for bolts, but I must have missed that section.

No, he didn't have pn's listed. I looked up bolt sizes for ARP fasteners, that is where I got those part numbers.

 

[dmoses42]

I'll have to check for the numbers for accessory bracket bolts later, I just got "honey-do'd..."

 

[toddz69]

The 3 bolts for the driver's side bracket are 3/8". They are laying on my garage floor and my calipers were 2 feet away .

[dmoses42]

Ok, so the accessory bracket bolts are:

652-2750
652-4250
652-2250 or 2500, Viper's write up showed it as 3/8-16x2.375 but ARP makes them in 1/4 inch increments. So one will be 1/8 short, or 1/8 longer.

653-4250 (need 4, but Jegs shows it as discontinued? Would come as a pack of 5 if available.)

All the part numbers I listed come in blister packs (I think that's what they are called) with multiple bolts of the same size. And I didn't look up part numbers for the 3/8 and 7/16 washers.

I'm thinking about going doing the explorer serp, does anyone know if the 94/95 SN95 timing cover/water pump is the same as the explorer? I currently have 95 Cobra front dress (I think its the same as GT) and am trying to figure out if I need everything or just the brackets/accessories

 

[ntsqd]

I can't answer that, but in looking for a Stewart Components coolant pump for the Explorer it appeared to me that the late Mustang pump and the Explorer pump use the same casting. If they are not the same, they are remarkably similar. However, the fan hub is totally different. If the Mustang pump places the pulley in the location that the Explorer front dress requires that might open up some cooling fan options? That may be a dead-end, but I don't know of anyone who has explored it (no pun intended).

 

[Bitch'nBronco]

Yeah, I'm mostly doing it to go to try out a mechanical fan. My Volvo fans are good but I think its time for a change. This is all mostly triggered by a small oil leak I saw coming from the balancer bolt area. I probably don't need to do the swap, but while we're "Exploring," I might as well lol

 

[ntsqd]

A guy on an ancient yota 4x4 email list came up with the cleverest way to remove the front crank bolt that I've seen yet. Disable the ignition so that it can't start. Socket on the bolt, breaker bar with the handle resting on the driver's frame rail, extensions as needed for it to just sit there. Now bump the starter and watch that bolt spin loose. The nervous-nellies on the list were concerned for the radiator. I've never had even a close call, but an EB's radiator is in a slightly different location so caution is needed until proven to not be an problem.

 

[Broncobowsher]

I don't think the SN95 water pump has the threads for the fan clutch. You already have the pump, look at that. No threads, you can give up now.
