Hey Ron, I did some front-end work last year.

I found it handy to assemble the lower trunnion to the A-arms first, finger tight. Also, with the spring pan nuts/bolts kinda loose, to allow movement to align the upper trunnion.

Install the spring with the floor jack under the spring pan. Raise the jack compressing the spring, with the help of the weight of the car and it may come off the jackstand little too.

Now, swing the king pin assembly up, and with the allowed play/movement from the loose lower A-arms/spring pan, the upper trunnion can be assembled to the upper control arm/shock. The pinch bolt may need to be loosened and arms spread/pried apart to allow the upper trunnion to slide in easier.

Looks like you’re doing a great job, nice.

Another update to this story - I ended up trying several different approaches to get the right side suspension put together, but as it turns out the dent in the front crossmember was damaged enough to affect the assembly of the suspension and make it virtually impossible. This was verified when I put the left wide together and everything fit nicely.

Long story short a found and purchased a front crossmember on eBay. Will post again when this is all sorted out.

I sure am glad it's cold wintertime around here right now!

I received my front crossmember purchased on eBay. Looks to be in pretty good shape, dirt and surface rust.

Look at the attached picture of the original (left) and new crossmember. The bend in the original was pretty serious, don't think I would have ever made it work. Not sure how the car didn't seem damaged when I was driving it. The damage must have been there when I bought the car and it was missed.

I think I would be looking other front end damage as it looks like that car took a pretty good hit!.

It's been a while since I posted any updates. I attached a picture of how the new front crossmember turned out after cleaning, blasting and painting with POR-15. When I put the whole front suspension back together, everything fit pretty well. It looked like the front of the frame rail on the side that took the hit may have been bent very slightly, but when attaching the new crossmember back to the car, I only had to force in one of the four threaded studs, and it was not much of a "force". In the end it all went back together good and drives so much smoother than before. Thanks to all who helped me along the journey.

Bob, thanks, that was very helpful. As the old saying goes, a picture is worth a thousand words, and I felt I was getting conflicting answers.

It was kind of awkward for me to get the springs out and in by jacking under the a-arm. I eventually did it but it was definitely butt clenching. The car has to be high enough to drop the wish bone down far enough and pivot the swivel. Also putting it back on without scratching the newly painted wishbone. I bought the new swivels from MGOC. They are doing ok but the rubber seals and bolts provided were junk and already starting to dry rot. Did this last year. Refilled the shocks with jack oil from walmart. I used the black carbon poly bushings for most of the stuff but I think rubber is probably fine. Red poly for the cross member.
