    Hey all,

    So I recently sold my 1952 Olds 88 and acquired a '63 Olds 98. Sweet sweet car, incredibly clean. I could not be happier. Shooting for a full repaint before the season begins.

    That being said, another part of the plan is lowering. I have looked into Jamco, and it seems hard for me to swallow nearly $700 for a 3" kit when you can get stock springs and shocks for $300.

    Does anyone know of a spring/shock out there there would get me a 3"+ static drop? Like how the Ford guys are using Aerostar springs and getting a 3" drop. Would love to know if anyone else knows of a conventional spring/shock that would work. And no, I do not want to just cut coils.

    Thank you!

    Check to see what part number of impala springs are, then check interchange. If they will interchange, I ordered springs from hubbards impala that were 2 inches lower and Variable rate. they were the same price as stock replacements. I cut 1/2 coil on all 4 corners. 64.jpg
     
  3. I'm sure I've seen one these 98 coupes somewhere before, but I sure as hell can't remember when or where. There couldn't have a great number of these built in '63. I'd forgotten how much they looked like a Lincoln or full-size Mercury from a side view. Shouldn't take a whole lot to make this look like a unique, one-of-a-kind sled.

    Especially with a little bit snow on the ground. . . :rolleyes:

    Hey Clay, yes, you are correct. From what I have heard and read, only around 3200 were made? Don't quote on that, so I could be wrong. Pair that with the fact that the trans in these was a bit of a weak point, I am sure many dropped out of use and never went back. That is why I was so stoked to find one in such great shape! Below is the end goal, back the the all original white paint, and low slung.

    The 63 Big Olds has the same suspension as the big Pontiac so I would look in that direction. The Chevy is an X frame and totally different..

    There are spring catalogs that let you order the spring you want.. Most springs they sell today as factory are two or three inches higher that what the car came with..

    You could cut half a coil off the fronts and try some GM A body springs in the back..
     
  6. Well....since your doing a re paint...why not nose it and deck it..remove the side badge..some chrome reverse wheels and that thing would be a kool mild Kustom..

    Personally, I like the badging and trim on the Olds'. And as far as wheels and tires, I am on a budget. I'm just trying to be a little different in that department. I feel like everyone who does a 60s car does a Bellflower kustom. Which don't get me wrong, I love!! Just for the time being, this is the plan. I just really like the sinister look of black steelies and poverty caps, and the tires are fairly new.
     
  8. Be careful or you'll wind up with a car that rides like a log wagon. I have a 2" drop coils on a OT sedan and I hate it. Bottoms out on country roads, doesn't handle any better, tough as hell to get an alignment in spec. Get some nice 15 inch wheels instead. My 2 inflation-ravaged cents....

    Don't remove any badging. Danchuk is making a fortune from guys putting back on nosed and decked 55-57 Chev's of the past. It never goes out of style. I removed every thing I could before going to body and paint, even the interior rear seat and all side panels to get off the side trim. I was lucky I could lower the windows on there stops and take the whiskers off and new were available.
    Good luck and replace the trans with a th350 because I bet the rear gear is pretty high for an OD .
     
  10. That should be a Rotohydramatic 375 ...1:1 top gear ratio, no OD...

    You lower a long and low car like that another 3 inches you will quickly find out how many gas stations are on raised parking lots.

    I'm going to be starting an Air Lift system install on my 61 Super 88 this week. I'm pretty sure the chassis is very similar if not identical. That will give you all the drop you want.
     
  13. I had a '64 88 when I was a kid... springs were all on the shot side and it was lower than your car. It scraped everywhere, driveways, parking lots and I had to be mindful of raised sewer covers. Look up replacement springs in the Moog catalog, it will give you an idea on configuration, rates and sizing. Something 2" shorter with the same spring rate would be a start.

    I'd trade the hubcaps for chrome lug nuts on the black steel wheels..
