Guys, don't know if this will help, but...being relatively new to Defender ownership I have found a magical recipe when buying new parts; and I've bought A LOT since Christmas!
1. I check the component description/G number on LR Workshop diagrams, it's a first rate reference
https://www.lrworkshop.com/diagrams
2. I click the component number and let the LR Workshop auto search facility work for me, this is usually straight onto eBay
3. if I think the price is too high, or it's a low quality component I cut & paste back to Google and then buy elsewhere
Over the past months with the 90 refurb' I've saved many £100's + I always check the delivery dates and never buy from Craddocks as they always deliver late. As example, this evening I've bought new swivel kits, HD axle flanges, all new bolts front and rear, and 60mm stud set [they're slightly pricey
but I have a new set of Wolfies in the shed waiting to get dirty]. All bought through reputable suppliers with eBay shops...and it's all arriving by this coming Saturday
ps using the lowest price + P&P filter can save a small fortune
