How to convert this SQL into a LINQ QUERY - sql

Question

I am having trouble turning the following sql code into LINQ. I have it mostly working but I can't figure out how to get the revision from the items table which is gotten in those subqueries. Any help would greatly be appreciated.
Here is the SQL query:
SELECT
dbo.SerialOptCon.GROUPID, TopRevsion.RevName AS NAME,
dbo.SerailOptionNo.PartNo, dbo.SerialOptCon.PRICE,
0.00 AS DISCOUNT,
dbo.GroupConfig.CURRENCY,
'OPTION' AS TYPE, dbo.SerialModelGroupOptions.MODEL,
dbo.SerialModelGroupOptions.SEQUENCE
FROM
dbo.SerialModelGroupOptions
INNER JOIN
dbo.SerialOptCon
INNER JOIN
dbo.SerailOptionNo ON dbo.SerialOptCon.OptionId = dbo.SerailOptionNo.ProductOptionId
ON dbo.SerialModelGroupOptions.OptionPartNo = dbo.SerailOptionNo.PartNo
LEFT OUTER JOIN
dbo.GroupConfig ON dbo.SerialOptCon.GROUPID = dbo.GroupConfig.ID
LEFT OUTER JOIN
(SELECT itm1.PartNo, itm1.Revision, itm1.RevName
FROM dbo.Items AS itm1
INNER JOIN
(SELECT PartNo, MAX(Revision) AS Revision
FROM dbo.Items
GROUP BY PartNo) AS itm2 ON itm1.PartNo = itm2.PartNo
AND itm1.Revision = itm2.Revision) AS TopRevsion ON dbo.SerailOptionNo.PartNo = TopRevsion.PartNo
WHERE
(dbo.SerialOptCon.GROUPID = '01d2b4d2-ad63-4eab-a83f-f31ea0f6274b')
AND (dbo.SerialModelGroupOptions.MODEL = 'abcde')
ORDER BY
SEQUENCE
Here is the LINQ query that I have currently:
foreach (var item in priceGroupDetailsViewModels)
{
(from pmo in _context.SerialModelGroupOptionss
join po in _context.SerailOptionNos on pmo.OptionPartNo equals po.PartNo
join pop in _context.dbo.SerialOptCon on po.SerailOptionNoId equals pop.SerailOptionNoId
join con in _context.GroupConfig on pop.GroupId equals con.GroupId
into p
from pmp in p.DefaultIfEmpty()
join it in _context.Items on po.PartNo equals it.PartNo
where pmp.PriceGroupId == item.PriceGroupId && pmo.Model == item.Name
select new OptionsDetails
{
GroupId = pop.GroupId,
PartNo = po.PartNo,
Currency = pmp.Currency,
Sequence = pmo.Sequence,
Description = it.Description3
});
}
