I've got whatever the local motor spares sells...make sure you have the washers ..and as mentioned..a straight edge to make sure they bolt holes aren't distorted .over tightening does this.
Just converted mine to wishbones..sold all the sp stuff on..but can remember roughly what they looked like
Post some pics or I'll swing by one day for you and have a look
Go to autotronix in Dinnington..speak to Clive. They've done mine and many others.
Had mine done 4 weeks ago..cost less than 100 quid..depends what's involved though
Having a sort out
Got an original pinto sump and pick up pipe.
And a rack from my oe sliding pillar set up.
20 quid each..collect barnsley or south Yorkshire meet
Can post at cost if needed
you can use a normal washer as long as its a snug fit..
although im unsure if its actually needed.. depends if the drive can slide up into the dizzy..always worth playing safe though
I take it you mean the washer half way down the pump driveshaft ..if so
an internal serrated shakeproof washer slid down the shaft will do it perfectly if its a snug fit
