Thanks for the picture, great help. I got a better look at my 77 block tonight vs the 93 block and these are the pictures Ive recorded. The pivot is for sure cast into the block, I thought about drilling the 93 block and tapping but it doesnt appear as if there is enough meat on the block to do so. So I have 2 remaining thoughts but prolly will not come to a conclusion until the old motor is pulled and I can remove that and measure it more. Solution #1 - To fab a braket out of 1/4" plate and bolt it to the block using the exsisting 3 holes close to that corner... #2 From what I can tell would be to got with an 86-87 4spd bell housing setup for hydraulic clutch and convert this. CHECK OUT THE PARTS LIST ON THIS LINK, this guy put a FI 5.0 mated to a NP435 using an 86 F-series bellhousing and stuffed it into a freaking Heep,..... lol sorry Jeep..( http://www.bc4x4.com/tech/waterman/bbill.cfm )..I thought it was cool.... OPINIONS??? Honestly the mecanical one feels good and works well and a hydraulic retrofit will just open a can of worms especially if something breakes on the trail. So i think Im going to try #1 first, plus its way cheaper cause Ill make my own.

Updated pictures and I think I found the solution for the clutch dilema... One I pulled both engines and was able to closely examine the blocks I think that there is plenty of room for me to drill and tap the 9/16x12 hole in the side of the block.. Here are some closer pictures, what do you guys think?? Also LMC Truck has all of the replacment mechanical clutch parts and they are next to nothing as far as comparing to the cost of switching to hydraulic. I think I can buy the tap and the bushings and hardware for less than the clutch of the slave cylinder alone. Plus it is going to be way easier and more reliable.

I tapped it yesterday and it turned out perfect, I used the center line of the tranmssion to block bolt on that corner as a refference point. Drilled the hole to 31/64' with several smaller pilot holes first and ran the 9/16 - 12 tap through it without any issues and looks exact to the older block. LMC truck carries all of the replacement hardware for the older mechanical setup so it looks like the biggest hurdle Ive come across so far was solved by an $8 NAPA tap and $11 drill bit and about an hour of my time. Pretty freaking awesome compared to the amount of time and cost associated with converting to hydraulic, and the fact the mechaincal clutch has always worked flawlessly, and much easier to fix on a whim out on a trail in the middle of no where. The new replacement motor should be refreshed and ready to go back in the hole, hopefully by next weekend. ***By the way does anyone need any of my old parts????????? I have a really cool custom power steering pump bracket I made out of the old one to switch to the newer style P/S pump....SEE THE PICS, THE BRACKET KICKS ***.

Just wanted to share some updated pictures with the clan... Most all of the harness is wired into the truck, the new motor has been freshened up and recieved a new coat of paint. Ive already ran the fuel lines from the 93 into the 77 and should be swaping in the 93 tank this weekend. Front what I can tell the gas tanks are almost identical as well. Pretty crazy all the common components and bracketry between the 20 year span. Could someone post a picture of theyre enegine on theyre 4.9???? Mainly the throttle cable braket and cable routing. I forgot how this one went.

Some more updated pictures from a Saturday in the shop... The fuel tanks between the trucks are almost identical. I took this pic with the 93 tank installed in the 77 to show where I had to clearence the crossmember to acess the lines at the top of the tank but once I did it looks factory. I used the stock metal supply and return lines from the 93, they were a little long and had to be bent to fit, better too much than not enough, PITA though. The 93 was a long bed with dual tanks, mine is a regular bed. Also check out the throttle cable, the bolt pattern of the flange and the plastic cable snap clip are the exact same as well. The 93 cable has a 45 degree tilt at the end of it and was about 1" longer. A trip to ACE was a fix for that, 2 steel spacers, and 2 - 1/4" X 1x1/2 sheet metal screws with two washers at the top bolt to adjust the angle did the trick. Oh I did have to open the center pass through in the 77 bracket because of the angled plastic. All hooked up nice and snug to the 1977 factory gas pedal and throttle bracket and it has full travel. Still would like to see how this throttle cable bracket mounts to the intake cause I cant remember. Amazing how little stupid **** like that will stump you. As far as the wiring for the fuel pump I jerked the factory harness from the 93, pulled it apart, kept the 3 wires I needed for the rear pump and put some fresh loom on it. I'M sooooooo glad I bought a whole truck when doing this swap, it would take years to do it piecing it all together with a ton of ordering and trial and error.
