    Can this plug on the back of a big block oil pump be replaced with a recessed plug? Are they NPT threads?

    No it's a straight thread. And no I would not replace it with a recessed plug. It is recessed on the inside where the relief spring fits in it.

        No. I'm just contemplating removing the front motorplate in my 66 Dart and making up a set of solid mounts instead. It shouldn't be a problem, but figured I'd ask since I've never taken apart a big block oil pump before. That plug is awfully close to where the mount will be.

        If you fab your mounts with factory mounts there is plenty of clearance. If you need any mounts let me know. I've got stuff kind of hidden away right now, but can always find a set. We'll be back up that way on Feb. 6.

        Thanks Jim! I may have to take you up on that offer. It'd be nice to have a couple brackets bolted to the block to be able to build off of.

        Do you have any that take the old biscuit style mounts?

        Yes, the only spares I have are biscuit mounts. I'll look around this weekend. Also still debating about going to the swap meet in Stockton next Sunday.

        If you find some that I could make work, that'd be great! Just let me know. I'll be curious to hear how the Stockton swap meet is. Unfortunately, I can't make it.

        Looks good! That would be a good starting point to build a mount for my 66. Here's what I'm workin with:

        The passenger side is even more straight forward:

        sometimes a truck mount works well on l side This allows youto focus on l side and pinion angle

        I pulled out a pair of mounts today before the rain hit. I'm on the fence on the swap meet, but we're heading to Grass Valley on the 6th for my granddaughter's birthday.

        Thanks Jim! Would it be possible for you to shoot me a photo? I should be around the weekend of the 6th. I could meet you somewhere too if that works easier for ya. Let me know what you want for them too.

          Yeah, I'll get some pics. I'll let you know what our schedule is. How's $40 for the pair?

            That'll work for me. When you get a chance, shoot me a photo or two. Do you know what application they're for? Thanks Jim!

            Pretty much all B/E body from the mid-60s (or before) through the early 1970s (spool mounts came out on those cars in 1974). Also found on some late-60s through early-70s c-bodies (not sure on those years, but also ended in 1973).

              Thanks Jim. I think using one of those on the driver's side would make things easier for me. Since the driver's side engine block lugs are directly above the flat mounting surface, I'll probably need to use something else for the passenger side - like a -62-65 b-body style. Got any of those by chance?

              Jim’s mounts are 66-72 B,C and E body. The pass mount is a bolt in deal on the 67-72 A bodies with a V8 K member. You use the A body biscuit mount. The drivers side is the fun one. Kim

              On second thought, I can use both of them. If needed, I can cut and stack the pass one to make it work. I'll take them! I'll shoot you a PM.

              Thanks Kim. On the 66 I' building, the mounting pad on the K-member is directly below the lugs on the block - slightly different than the 67-72's. I'm pretty sure I can make it work though.

              Then u may have to drill different holes or maybe even turn the biscuit sideways. Kim

                I won't be using biscuits. It'll be solid mounted with newly fabricated mounts and I'll likely be drilling new holes.

                Hey Jim - those mounts worked out great. With a little modification, they turned into great BB early A mounts. I ended up going with poly bushings. I just have to finish bolting the bottom portion up to the K-member.

                  Nice. Beats having to reinvent the wheel on the engine side.
