The thick carriage bolts go through the front of the subframe and the long donor bolts go through the rear of the subframe, control arms and into the goblin frame.It has been a while and I have been very busy so I have not given an update in a while, but I have officially finished all my wiring, lights, computers, etc. I have most of the donor parts mounted that are body related and will be moving onto suspension hopefully very soon. I am trying to mount my subframe now but I am unclear about some specifics. I see that the K23C baggie is listed as subframe mounting hardware, however I am not sure in what manor the bolts are supposed to be used. They are only grade 8 and are also carriage bolts and I don't see anywhere where a carriage bolt should be used. From my understanding, I use the donor subframe mounting bolts in the rear, but I don't know what bolts go through the subframe and control arm bushings in the front of the subframe. I would really love it if any of you could share how you got your subframes mounted. Thanks!
The three bolts that mount to the motor will be from the baggie, I don’t remember the number. The three that mount through the subframe will be the long thin donor bolts. If I remember correctly the bag for the subframe will have nuts for those bolts. I can check when I get home tonight. I had to loosen all of the bolts mounting to the engine to get the 3 long donor bolts lined up.I got those in and I am going to wait to torque them down until I get all my fasteners related to the subframe at least started but now I have reached another question. I am trying to attach the rear solid trans mount (the one with three holes on the subframe side and three on the engine side) and I am not sure which bolts to use or how to get the holes to lineup properly. I noticed that the K23C baggie has 5 shorter bolts and large washers that I have not used at all and am not sure where they go. Any ideas?
I have to force mine in, they don’t want to line up. First, I loosely mount the three bolts into the transmission. Then, I have to take a big screw driver and tweak it until I can getwo of the long bolts through the subframe and swan neck portion of the mount. Tighten it up enough to hold and then put the third long bolt through.Ok so does that mean I received the wrong hardware bag? Even if that is the case I'm still unsure what to do about the long bolts and the bracket not entirely lining up properly.
